Replace calls to sec_reg* helpers with direct usage of regmap API. The
sec_reg* helpers are error-prone as they mix u8 with unsigned int and
order of some of parameters (val and mask in sec_reg_update()).
Also the helpers do not give any way of useful abstraction as they just
call corresponding regmap function.
This patch replaces:
- sec_reg_read() with regmap_read(),
- sec_reg_write() with regmap_write(),
- sec_reg_update() with regmap_update_bits().
