    tegra124: More improvements to the clock initialization macros.
    
    Consolidate the register setting clrsetbits_le32 call to simplify the macros.
    Add a check for bits of the divisor being dropped. The clock source registers
    will throw away bits that aren't supported, so we can check for divisor
    overflow by checking for dropped bits.
    
    BUG=None
    TEST=Purposefully tried to set a clock to a rate which overflows its divisor.
    Verified that the check triggered. Booted on nyan. Verified the TPM i2c bus
    frequency was still correct.
    BRANCH=None
