OMAP4: PM: Disable work around for CPU1 onlining from OFF/OSWR state

CONFIG_OMAP4_PPA_CPU1_ONLINE_BUG should be disabled for PPA > 1.6.4

If PPA version cannot be updated beyond 1.6.4 (PPA <= 1.6.4), this patch
should not be applied.

Note:
Patch with change Id I82c5880ec2d9a98a54755dfbd01aa981cfed9852
introduced this work around by default for all devices using PPA
version 1.6.4 or older.

OMAP4460: OPP: add recommended conservative s/w margins

Considering the delta from Class 3 to Class 1/1.5, a recalibration
delay of 1 week, and maximum operating temperature range,
update per OPP s/w margins as per conservative safe margins.

Further characterization is in progress to provide more optimized,
yet safe margins and these numbers are with the data collected
as of current time.

OMAP4: OPP: Add High Performance CORE OPP set

OMAP4470 specification defines two sets of CORE OPPs:

   OPP  |    Low Power     | High Performance |
        | Volt | L3  | SGX | Volt | L3  | SGX |
--------+------+-----+-----+------+-----+-----+
 OPP50  | 0.96 | 100 | 154 | 0.96 | 117 | 191 |
 OPP100 | 1.13 | 200 | 307 | N/A  | N/A | N/A |
 OPP-OV | 1.23 | 200 | 384 | 1.23 | 233 | 384 |

High Performance set is enabled if CORE DPLL frequency is higher than 1600MHz.
OPP100 is absent in High Performance set.

OMAP4: clock: Extend L3 clock dependencies to cover 4470

Currently L3 OPP50 frequency is hardcoded to 100MHz.
But OMAP4470 has High Performance CORE OPP set where L3 OPP50 is 116MHz.
This patch exetends L3 clock dependencies to cover 4470 HP CORE OPP set.

Assumption made that DDRPHY freq is always 4x L3 freq.

OMAP4: TEMP_SENSOR: Additional checking for context lost scenario

Calling pm_runtime_get_sync() function during driver initialization
leads to formation of the resume request, which will restore
registers values using not yet initialized data.

To prevent invalid data writing into registers at the early
stage of booting, additional checking has been added.
