Few cleanups to reduce code indent,
Add pbias_regulator support and adapt omap_hsmmc to use pbias regulator

I tested on both OMAP3630 (Overo Storm) and OMAP4430 (DuoVero). The
rootfs is mounted on mmc1 and works as usual. Here is what I can see:
- pbias-supply is parsed from DT
- VMMC1 is set to 3V
- According to the debugfs entry, we are working at 3V signaling
- By dumping CONTROL_PBIASLITE, bit MMC1_PBIASLITE_VMODE
(PBIASLITEVMODE0 on OMAP3) is set to 1 (-> 3V)
Do you see any other tests that I could run to validate your patches?
Nope, Stefan has tested the other use case of detecting sd card at kernel
without any sd card/pbias activity at u-boot.
Otherwise:

Thanks Florian, Stefan for Testing.
