[PATCH v2] host: omap_hsmmc: style: Simplify bool comparison and conversion

[Yang Li]

Fix the following coccicheck warning:
./drivers/mmc/host/omap_hsmmc.c:297:6-25: WARNING: Comparison of 0/1 to
bool variable

According to the context, vqmmc_enabled is more suitable for bool
type.

Changes in v2:
 -clean up all use of "pbias_enabled", and do the same clean up for
"vqmmc_enabled".
