Commit 72f381ba05 (omap3: Remove VMMC2 regulator on IGEP v2)
removed an unused regulator entry, but left the second MMC channel
(used by the Libertas WLAN module) without link to power regulator.
This causes the SDIO module to fail being detected.
This patch adds the two regulators that actually feed the WLAN module
(1v8 from the TWL4030 VIO LDO, and a fixed 3v3). With that patch, the
second channel is properly detected. Details of the power supply
implementation were kindly provided by Enric Balletbo i Serra.
Also change vmmc1 to use symbolic names instead of direct device
reference.
Tested on an IGEPv2 Rev-B.

Implement errata handling to use flags instead of cpu_is_* and
cpu_class_* in the code.
The errata flags are initialized at init time and during runtime we are
using the errata variable (via the IS_DMA_ERRATA macro) to execute the
required errata workaround.

These low level read/write functions along with static register offset

When we soft-CPU hotplug a CPU, we reset the stack pointer and
jump back to start_secondary(). This allows us to restart as if
the CPU was actually reset.
However, we weren't resetting the frame pointer, which could cause
problems with backtracing. Reset the frame pointer to zero (which
means no parent frame) just like the early assembly code also does.

There are 2 versions of the timrot on Freescale MXS-based SoCs.
The v1 on MX23 only gets 16 bits counter, while v2 on MX28
extends the counter to 32 bits.
The implementation uses two timers, one for clock_event and
another for clocksource. MX28 uses timrot 0 and 1, while MX23
uses 0 and 2.

When a CPU is hot unplugged, the generic tick code cleans up the
clock event device, but fails to call down to the device's set_mode
function to actually shut the device down.
To work around this, we've historically had a local_timer_stop()
callback out of the hotplug code. However, this adds needless
complexity when we have the clock event device itself available.
Explicitly call the clock event device's set_mode function with
CLOCK_EVT_MODE_UNUSED, so that the hardware can be cleanly shutdown
without any special external callbacks. When/if the generic code
is fixed, percpu_timer_stop() can be killed off.
