Fix disabling printk's build error.

Disabling printk's via CONFIG_PRINTK in the menuconfig gives the build error:

This was tested on both the 4AI.1.2 and 4AI.1.3 releases with the same result.

OMAP4: EMIF: code cleanup and clarification

Removed unused fields of emif_regs structure and
functions that initialize or change them.

Also changed few names of emif_regs members
to match register names.

This made the code easier to understand and read
as well as made it a little bit faster

OMAP4430/60: EMIF: errata: Prohibit usage of Power-Down mode

A ZQ calibration long command is issued every time on exit
from active power-down and precharge power-down modes
when EMIF is configured to use Power-down mode
(EMIF_PWR_MGMT_CTRL.REG_LP_MODE=0x4).

Due to very short periods of power-down cycles, ZQ calibration
overhead creates bandwidth issues and increases overall system
power consumption.

As result, the guideline is to not allow Power-down mode and,
therefore, to not have set the
EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE bit field to 0x4.

OMAP: rfkill driver for ST-E modem

Driver skeleton aimed at controlling ST-E modem rfkill switches.
It will bind to relevant modem devices drivers once registered, and
create relevant sysfs entries.
Preliminary version, actual rfkill switch control is not implemented.

twl6040: errata: PDMUP State In Sleep/Deep Sleep Mode

When AUDPWRON is set to 0 at any time in the IC operation to
put it into sleep or deep sleep mode, there is a finite probability
that the value of PDMUP could be at logic 1 (VDDVIO). In this state,
the resistive pulldown on OMAP on this pin results in a current drain.

Adding new impacted revisions (ES1.3, ES2.0, ES2.2) to errata workaround.

OMAP: UART: Enable RTS line control in UART driver

On suspend path single data byte can be losted by UART.
For prevent the issue we need to enable RTS control in
UART driver. Rising the RTS line right after suspend
routine start preventing send additional data from client
and thereby preventing data lost.
Since this featute was already implemented in UART driver
and depends of platfrom setting that doing this via
platform data and just for UART1.
