mmc: core: Fix hangs related to cards initialization

This patch is ported from upstream.
Actually we should understand this patch only can fix the hangs related
with cards initialization part. Insert/remove of cards can not only
cause cards initialization, but also some operation in mmc stack block
layer and host layer, which this patch cannot prevent can do nothing with.

Below is the original commint:
----------------------------------------------------------------
mmc: core: Fix hangs related to insert/remove of cards

During a rescan operation mmc_attach(sd|mmc|sdio) functions are
called. The error handling in these function can trigger a detach
of the bus, which also meant a power off. This is not notified by
the rescan operation which then continues to the next attach function.

If a power off has been done, the framework must never send any
new commands to the host driver, without first doing a new power up.
This will most likely trigger any host driver to hang.

Moving power off out of detach and instead handle power off
separately when it is actually needed, solves the issue.

mmc: core_sdhci: emmc mutex support for medfield

One of the Medfield eMMC controller (PCI device id 0x0823, SDIO3)
is a shared resource used by the SCU and the IA processors.
SCU primarily uses the eMMC host controller to access the eMMC device's
Boot Partition, while the IA CPU uses the eMMC host controller to
access the eMMC device's User Partition.

After the SCU hands off the system to the IA processor, the IA processor
assumes ownership to the eMMC host controller. Due to absence of any
arbitration at the eMMC host controller, this could result in concurrent
eMMC host accesses resulting in bus contention and garbage data ending up
in either of the partitions.

To circumvent this from happening, eMMC host controller locking mechanism
is employed, where at any one given time, only one agent, SCU or IA,
may be allowed to access the host. This is achieved by implementing
Dekker's Algorithm (http://en.wikipedia.org/wiki/Dekker's_algorithm)
between the two processors.

Before handing off the system to the IA processor, SCU must set up three
housekeeping mutex variables allocated in the shared SRAM as follows:

eMMC_Owner = IA (SCU and IA processors - RW, 32bit)
IA_Req = FALSE (IA -RW, SCU - RO, 32bit)
SCU_Req = FALSE (IA - RO, SCU - R/W, 32bit)

There is no hardware based access control to these variables and so code
executing on SCU and IA processors must follow access rules of
Dekker's algorithm. Detail info about this algorithm can be found in
comments and code of this patch.

gpadc: fix sample result error

During stress test, ADC results have some bad valules.
Driver has a race condition issue. It initializes the output data to 0 first
without any lock. And the caller may access the output pointer before function
return.

This patch moves the output data initializing code inside mutex protected period.
And it also adds a limitation which forbid caller to access output pointer
before function return.

gpadc: prevent CPU from S0i3 when ADC is active

Under the following scenario:
1. IPC1 request sent to SCU
2. PM_CMD s0ix entry request sent to SCU
3. MWAIT C6 abort (or no attempt at MWAIT C6)
If steps #1 an #2 are sufficiently close (maybe within 200us) there is
a possibility that SCU will handle the PM_CMD first and begin waiting on an
ack_c6 response from the MWAIT that is expected. Since the MWAIT never comes
(or is aborted) SCU will have to eventually time out before being able to move
on and handle the IPC1 request.
