[PATCH v2] clocking-wizard: fix a schedule during spin lock acquisition

[Hao Peng <flyingpenghao@xxxxxxxxx>]

From: Peng Hao <flyingpeng@xxxxxxxxxxx>

when the interrupt is disabled and the spin lock is acquired,
calling read_poll_timeout will trigger the schedule, which should
be replaced by read_poll_timeout_atomic.
