kernel will disable SD clock when there is no data
transfer, so need to enable SD clock before reboot for
SD boot mode

The ASRC cann't work when the SPDIF RX is employed to drive the input
part of the ASRC.
The root cause is miswritting "reg |= 7 << AICPA;" as "reg | 7 <<
AICPA;".

Trying to free already-free IRQ 240 causes the warning dumped out
when boot up the kernel.
Return the error code in the probe function, which indicats the
failure of the platform driver probing. Then the platform driver remove
function will not be called, avoiding of freeing an already-free IRQ again.

In the rng_test_driver.ko and rng_test, RNG_REGISTER_PEEK_POKE flag
should be defined, otherwise, the rng_read_register() and rng_write_register()
functions will not be defined. And the flag RNG_REGISTER_PEEK_POKE depends on
CONFIG_RNG_TEST_DRIVER, which is not set in the default config file.
Resolve the problem by setting the CONFIG_RNG_TEST_DRIVER.

Since the true CAS latency can only be changed subsequently
if WRITEMODEREG is set, and since WRITEMODEREG is not currently
used in the BSP, these 2.5 settings in emi.inc don't really matter.
However, they may give a lot of confusion for whoever is debugging
the EMI driver, since the HW_EMI register will read one thing,
while the controller is doing another thing

The ak4647_codec is not initialized as there is no ak4647 codec existing
on MX35 board. In the 31 kernel, the card and codec drivers are
registered separately, and there is no check whether the codec is probed
successfully or not. On MX35 board, the card is sucessfully registered,
but there is no ak4647 codec. In this case, the system will crash if the
system try to invoke the codec's resume function.
To resolve the problem, add a check in registering the card. If the
codec does not exist, give up registering the card either.

wm8580 is using regulators that can't change state. The
regulator driver doesn't handle this case well so it crashes
