drivers/power/qpnp-charger.c: fix charging issues with non-Oppo chargers

1. refactor the current limiting code to use existing temperature sensing
   capability rather than some arbitrary 1 minute loop

2. removed all current check loops below 900mA. Due to inaccurate ADC input
   readings, some non-Oppo wall chargers are mis-identified and their charging
   capabilities severely limited by the over protective driver

USB data port charging are unaffected by these changes

msm_serial_hs: Dynamic allocation of port structures

This patch allocates the msm_hs_port structures
dynamically during probe and cleans up during exit.
The msm_hs_get_uart_port function now looks up the
uart_state data structure to find the right uart_port.

qseecom: update clock ref count when bus scaling timer is running

When there are multiple enable/dislable clock operations, ce clock
ref count is not updated correctly when the timer to disable clock
is running. Specifically, the ref count is not decreased when the
old operation is finished and then we reset clock for the new enable
clock. Thus, the ce clock is not disabled after all operation are
completed due to incorrect clk ref count. We make a change to
decrease clock reference count before reset timer, when the timer
is running, then clock is disabled when all ce clock operations
finish and the timer expires.

mmc: sdhci: add asynchronous interrupt support for sdio card

Some controllers can gate the clock to save power
even for SDIO cards. In such cases, an asynchronous
interrupt mechanism is used to receive interrupts
even when clocks are off.

This patch wakes up the sdio thread if interrupts
were received when clocks were off.

 * corresponding pm_relax have to be invoked
