[PATCH 22/30] rockchip: rk3399-roc-pc: Drop get_reset_cause() call

The Firefly ROC-RK3399-PC board configures power LEDs depending on the
global reset state register value in xPL phase. get_reset_cause() is
used to determine the reset cause.

Reset cause handling is being moved into the sysreset_rockchip driver
get_status() ops, with plans to not include such ops in xPL builds.

Read the global reset state register directly to determine reset cause
to ease the migration of get_reset_cause() to use the get_status() ops.
