Add additional information to determine the cause of binder
failures. Adds the following to failed transaction log and
kernel messages:
return_error : value returned for transaction
return_error_param : errno returned by binder allocator
return_error_line : line number where error detected
Also, return BR_DEAD_REPLY if an allocation error indicates
a dead proc (-ESRCH)

With the global lock, there was a mechanism to acceess
binder driver debugging information with the global
lock disabled to debug deadlocks or other issues.
This mechanism is rarely (if ever) used anymore
and wasn't needed during the development of
fine-grained locking in the binder driver.
Removing it.

When begin connecting to PC in device mode, the driver will hold a
wake lock to prevent system from entering deep sleep. If it fails
to connect to PC or doesn't detect the vbus, the driver will suspend
usb phy and disable usb clk, and release the wake lock.
If unlock the wake lock first, system may enter deep sleep before
suspend usb phy and disable usb clk. Then wake up system by pull
out the usb cable, it may cause usb interrupt abnormal.
TEST=rk3126c connect the usb charger into the charging interface,
after the system entered deep sleep, pull out the usb cable with

From Rockchips fractional divider description:
3.1.9 Fractional divider usage
To get specific frequency, clocks of I2S, SPDIF, UARTcan be generated by
fractional divider. Generally you must set that denominator is 20 times
larger than numerator to generate precise clock frequency. So the
fractional divider applies only to generate low frequency clock like
I2S, UART.
Therefore add a special approximation function that handles this
special requirement.

Fractional dividers may have special requirements concerning numerator
and denominator selection that differ from just getting the best
approximation.
For example on Rockchip socs the denominator must be at least 20 times
larger than the numerator to generate precise clock frequencies.
Therefore add the ability to provide custom approximation functions.

[ Upstream commit 9f169b9f52 ]
When multiple front-ends are using the same back-end, putting state of a
front-end to STOP state upon receiving pause command will result in backend
stream getting released by DPCM framework unintentionally. In order to
avoid backend to be released when another active front-end stream is
present, put the stream state to PAUSED state instead of STOP state.
