[PATCH 25/58] tty/serial: Migrate msm_serial to use has_sysrq

[PATCH 25/58] tty/serial: Migrate msm_serial to use has_sysrq

[Dmitry Safonov]

The SUPPORT_SYSRQ ifdeffery is not nice as:
- May create misunderstanding about sizeof(struct uart_port) between
  different objects
- Prevents moving functions from serial_core.h
- Reduces readability (well, it's ifdeffery - it's hard to follow)

In order to remove SUPPORT_SYSRQ, has_sysrq variable has been added.
Initialise it in driver's probe and remove ifdeffery.
