Eugen Hristev 0be07872e3 spl: at91: add support for SPL_AT91_MCK_BYPASS
By default the configuration of the PMC is to have an external crystal
connected that requires driving on both XIN and XOUT pins.
The bypass configuration means that only XIN will be used, the SoC will not
do any driving, and the XIN needs to be provided with a proper signal.
This is the MOSCXTBY bit in the PMC main clock generator register.
The SPL needs to properly initialize the PMC registers before switching
to external clock signal and raising the clock to the cruise speed.

Also created Kconfig for this specific configuration.
By default this is disabled.
