From: Quanyang Wang <quanyang.w...@windriver.com>
The regmap subsystem use mutex lock as its default lock but this will
cause the error that calling sleeping functions in an atomic context
since the irq callbacks "irq_set_type/irq_mask/irq_unmask" for
siul2-s32cc are all using regmap_update_bits.
Add use_raw_spinlock flag to the regmap_config structure siul2_regmap_conf
can switch mutex lock to raw spinlock.
