There is a name collision between 'struct platform_driver
anatop_regulator' and 'struct anatop_regulator', which causes some
section mismatch warnings like below.

WARNING: vmlinux.o(.data+0x154d4): Section mismatch in reference from the variable anatop_regulator to the function .devinit.text:anatop_regulator_probe()
The variable anatop_regulator references
the function __devinit anatop_regulator_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

Rename 'struct platform_driver anatop_regulator' to
'struct platform_driver anatop_regulator_driver' to fix the warnings.

size field in reg.
