ASoC: wm_adsp: Fix some signedness errors in register access

base and sysclk_reg should be unsigned int, as that is what
regmap takes as a register address.

sysclk_mask is used to mask unsigned register values so
should be unsigned.

sysclk_shift is a shift value so is not allowed to be negative.
