armv7/snow: Remove unused modules in bootblock and romstage.
For Exynos/snow, cpu_info and power modules and also some parts of
the GPIO API (which require timer and pwm modules) are not used in the
current bootblock. Clock init only needs to be used if early console
is enabled.
Now our bootblock is 22420 bytes with early serial console and 11192
bytes without. Those include the 8KB BL1 region.
