mmc: core: enhance card removal judgement for slow removal

Function _mmc_detect_card_removed will be called to know whether
the card is still present when host->bus_ops->detect is called.
In current code, the return value of this function generally only
depend on the result of sending cmd13 to card, which may not safe
for card with detection support like slot gpio detection.
Because the communication status between host and card may out of
sync with the detect status if remove the card slowly or hands shake
during the process. The direct reason is the async between card
detect switch and card/slot pad contaction in hardware, which is
defined by spec.

The spec define card insert/remove sequence as below (both standard size
SD card and MicroSD card have the same sequence):
"Part 1 Standard Size SD Card Mechanical Addendum Ver4.00 Final,
Appendix C: Card Detection Switch" (Take normally open type as example)
a)SD card insertion sequence:
  The card detection switch should be turned on after all SD card
  contact pads are connected to the host connector contact pads.
b)SD removal sequence:
  The card detection switch should be turned off when the SD card
  is just going to be removed and before any SD card contact pad is
  disconnected from the host connector contact pad.

Below is the sequence when this issue occur (Take slot gpio detection
as example and remove the card slowly during the process):
1. gpio level changed and card detect interrupt triggered.
2. mmc_rescan was launched.
3. the card pads were still contacted with the slot pads because of slow
   removal. So _mmc_detect_card_removed and mmc_rescan think card was
   still present (cmd13 succeed).
4. card pads were discontacted from the card slot pads.
So the card was actually removed finally but the card removal event
has been missed by system.
The interval length between step 1 and step 4 depends on the
card removal speed. If it's longer than the detect work schedule
delay which is 200ms, this issue will likely happen.

This patch add the card detect status check in function
_mmc_detect_card_removed if cmd13 check succeed and host->ops->get_cd
provided. If get_cd detect no card present then schedule another detect
work 200ms later.

mmc: core: invoke low power mode if card is not present

If get_cd is defined and card is not present mmc_rescan
returns without invoking mmc_power_off. This would prevent
low-power modes.
Hence, invoke mmc_power_off if card is not present before
exiting mmc_rescan.

block: row: Fix crash when adding a new field in bio struct

When adding new field to struct bio there is a crash in the removed
code lines. This issue was introduced by commit
80a8f0f87bee18283e9ca0a8966ec97ad9f084e5 "block: row-iosched idling
triggered by readahead pages"

(Partly) reverting this patch till root cause is fixed (on FS level).

msm7x30: Allow to optionally enable the use of CMA for ION MM and PMEM ADSP heaps

Add two new config options to enable or disable the use of CMA in order
to dynamically or statically allocate the memory needed by ION MM and
PMEM ADSP heaps.
mogami/zeus: ifdef CMA changes

Allow disabling MM or ADSP CMA heaps
defconfigs: Update with latest changes

Enable the option to use CMA for ION MM heap and for PMEM ADSP heap.
mogami/zeus: Use a higher memory allocation if CMA is used for ION MM heap

When CMA is used for ION MM heap, it could be required that a higher amount of
memory is temporarly allocated while starting the playback of some HD videos
or while re-encoding a long video before sending/sharing it with an app
(for example WhatsApp).

Also bump the non-CMA MM size to 0x1C80000
mogami/zeus: Adjust ION SF heap size
msm: camera: Assign Null to unmapped addresses

Observed unhandled virtual addresses with all the camera drivers
while performing reads and writes to the ioremap addresses in different
scenarios, Hence assigining NULL to all the hardware remapped addresses
immediately after the iounmap calls
