[PATCH 1/4] ASoC: fix regwmask

[PATCH 1/4] ASoC: fix regwmask

[Gyeongtaek Lee]

If regwshift is 32 and the selected architecture compiles '<<' operator
for signed int literal into rotating shift, '1<<regwshift' became 1 and
it makes regwmask to 0x0.
The literal is set to unsigned long to get intended regwmask.
