Some variants of the i.MX53 do not allow to run at 1GHz, so
pass a cpu frequency parameter to the lowlevel init function.

Reimplement the code from lowlevel.S in C. It is run
from SDRAM anyway, so we can safely do this initialization
in a regular barebox environment instead in Assembly.

- move code which can be shared between i.MX53 and i.MX51
to a common file
- rename mx53_init_lowlevel to imx53_init_lowlevel
