This patch adds cpu hotplug support for OMAP4430. Only CPU inactive
state is supported as a low power state in the basic hot-plug support

This patch adds a secure API to read AuxCoreBoot0 register to
check the cpu boot status. It also moves the other smc APIs
to common omap44xx-smc.S. This APIs should not be marked as
__INIT because we need these to be present for CPU hotplug

Errata i202 (OMAP3430 - 1.12, OMAP3630 - 1.6):
UART module MDR1 register access can cause a dummy underrun
condition which could result in a freeze in the case of IrDA
communication or if used as UART, corrupted data.

Workaround is as follows for everytime MDR1 register is changed:
* setup all required UART registers
* setup MDR1.MODE_SELECT bit field
* Wait 5 L4 clk cycles + 5 UART functional clock cycles
* Clear the Tx and RX fifo using FCR register

Note: The following step is not done as I am assuming it is not
needed due to reconfiguration being done and there is no halted
operation perse.
* Read if required, the RESUME register to resume halted operation

Based on an earlier patch at:

It seems that the battery cover sensor in Nokia N900 is powered from the
V28 domain. Now if this regulator is disabled it causes that the gpio 160
reads only zero which effectively causes uSD removal detection.

Currently the bootloader enabled V28 is kept on but this may change in the
future according to comment in
drivers/regulator/core.c: regulator_has_full_constraints.

Also if there are any consumers on the V28 domain doing regulator_enable
regulator_disable cycle the V28 will be disabled after that.

Prepare for these by defining the V28 as always_on regulator.
