msm: dcvs: fail gracefully if TZ does not support dcvs

If dcvs attempts to initialize on a system where TZ does not support
dcvs, it will eventually cause a crash. Prevent this by disabling
dcvs if TZ does not successfully initialize its part of dcvs.

input: synaptics_i2c_rmi4: Add low power mode

Enable regulators to go into low power mode when
device enters suspend, to save power.  In resume,
return regulators to full power.

input: synaptics_i2c_rmi4: allocate memory for interrupt status

In synaptics_rmi4_i2c_read, intr_status is a char variant.  So
if num_of_intr_regs > 1, then intr_status will write 2 bytes.  This
will destroy the stack, so avoid it.

msm_serial_hs: Use RFR GPIO to communicate remote uart

CTS and RFR GPIOs are used for hardware flow control between
two uarts. RFR GPIO provides current status of uart receiver
to remote uart and based on this remote uart sends data.
Hence use this functionality to prevent remote uart to send
data when port is being opened, baud rate change operation
is in progress and port is being closed.

This change also set UART_DM_MR2 (Bit: 8 and 9) before
configuring connected UART GPIOs to prevent RX_BREAK character
and any character having PARTIY or FRAMING error which can be
generated due to configuration of those GPIOs. Allows those
character once port is opened successfuly.

This change also zeroed uart rx software buffer which would
help to see how many bytes copied by ADM from received data
with UART RX FIFO to this memory. This would be useful if
there is any Rx Stall issue is seen.
