    libpayload: Replace majority of timer drivers with a generic one
    
    Currently every non-x86 platform supported by libpayload needs to
    provide its own timer driver. Most of the ones we have accumulated there
    look almost identical: For the frequency, return a preset constant. For
    the value, read a 32-bit register, possibly read another 32-bit register
    and shift+OR it with the previous one, then return that.
    
    Let's replace this with a single .c file that can easily handle all of
    those cases. Menuconfig convenience can still be maintained by providing
    several presets that select different defaults for the driver's
    configuration options (register address(es) and frequency).
    
    Removes an "enabled" check from Samsung MCT driver since coreboot always
    unconditionally enables that timer anyway.

    TEST=Booted Oak and Veyron, observed how dev-mode delay was still ~30s
