[PATCH v2 2/2] spi: spi-fsl-lpspi: Switch to SYSTEM_SLEEP_PM_OPS()

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <festevam@denx.de>

Replace SET_SYSTEM_SLEEP_PM_OPS with its modern SYSTEM_SLEEP_PM_OPS()
alternative.
    
The combined usage of pm_ptr() and SYSTEM_SLEEP_PM_OPS()
allows the compiler to evaluate if the runtime suspend/resume() functions
are used at build time or are simply dead code.
    
This allows removing the __maybe_unused notation from the runtime
suspend/resume() functions.

Changes since v1:
- Pass pm_ptr().
