OMAP4+: Add ability to store reboot reason

Bootloaders need to know when their platforms do a reboot.
The only memory that is retained is SAR ram accross reboots,
provide ability to store the reboot reason in a standard location
in the SAR memory (using the last 0xf bytes in SAR BANK1 ram).

This is now populated with the string "normal" if the reboot
is due to ordinary reboot commands, if the reboot reason is
for other reasons, such as bootloader or recovery as is the
case with Android systems, this stores the same.

NOTE: bootloader should be updated accordingly.

OMAP4: HSOTG: Improved HSOTG USB EYE diagram

1. Added the ability to improve HSOTG USB EYE diagram.

 solution #1: (all 44XX CPUs family)
   Improvement of 2-3% in EYE diagram opening by playing slightly on USB
   driver output impedance.

 solution #2: (4430 CPUs)
   Improvement of up to 8% in EYE diagram opening has been accomplished by
   decreasing the internal termination impedance by increasing the SWCAP
   trim code in USBPHY_USB2PHYCM_TRIM register to 0x24.

2. Added menuconfig option for this feature:
   'System Type'--->'OMAP 44XX HSOTG Eye diagram correction'

OMAP: Support for Android RAM console

Android's RAMCONSOLE framework is handy framework which allows
saving the kernel printk messages to a buffer in RAM, so that
after a kernel panic they can be viewed in the next kernel
invocation, by accessing /proc/last_kmsg.

This obviously needs DDR to be in selfrefresh mode. Board files
which have relevant support need to enable CONFIG_OMAP_RAM_CONSOLE
and call omap_ram_console_init with relevant parameters for this
to function.
