USB: msm_otg: Fix host mode suspend bug

Capturing BSV bit before ID test msm_otg_set_vbus_state()
is leading to return suspend call without entering
USB into LPM. In host mode since there is no need for
BSV check, clear the BSV bit so that USB suspend can
go through.

This happens when a target enters host mode with no devices
attached, USB OTG will never enter LPM, as the BSV bit will
always be set.

USB: msm_otg: Fix a bug in charger detection procedure

USB PHY is put into non-driving mode and pull-down resistors on DP
and DM are disabled before starting the charger detection.  The
PHY is put into driving mode at the end of the charger detection
without enabling the pull-down resistors.  Due to this DP is
pulled high when a dedicated charger is connected.  USB controller
is not allowing PHY suspend if line state is non-zero when charger
is connected.  Enable pull-down resistors at the end of charger
detection to resolve this issue.

ARM: 7583/1: decompressor: Enable unaligned memory access for v6 and above

Modern GCC can generate code which makes use of the CPU's native
unaligned memory access capabilities.  This is useful for the C
decompressor implementations used for unpacking compressed kernels.

This patch disables alignment faults and enables the v6 unaligned
access model on CPUs which support these features (i.e., v6 and
later), allowing full unaligned access support for C code in the
decompressor.

The decompressor C code must not be built to assume that unaligned
access works if support for v5 or older platforms is included in
the kernel.

For correct code generation, C decompressor code must always use
the get_unaligned and put_unaligned accessors when dealing with
unaligned pointers, regardless of this patch.

msm: spm: set vdd directly for current cpu

In cases where a cpu is setting vdd for itself we need not

Without this change when CPU calls for itself when interrupts

msm: mdm: change where ssr_count is decremented

In fusion targets with more than one external modem, where
the modems are restarted together, ssr_count keeps track of
how many modems are still left to be completely restarted so
that any new SSR requests would be rejected until all modems
are restarted. Ssr_count should be decremented when the SSR
module sends the SUBSYS_AFTER_POWERUP notification instead of
during the powerup callback in order to be in sync with the
state of the SSR module.

msm: kgsl: Force the ME off before reading the microcode

On A3XX reading the microcode while the CP is running is dangerous
beyond words.  By setting the offset address for the read, we are
essentially changing the instruction pointer for the ME while it
is running causing opcode errors, gpu faults and/or system errors.

We do not want to stop the CP at the beginning of the snapshot
process beacuse doing so changes the RBBM status and the state of
the CP registers which may damage the debug effort.  But by the
time we get to the microcode read we no longer care about the state
of the registers so we can freely halt the ME just before starting
the read.
