Default setting is at 48MHz.
For PLL frequency at 24MHz:
1. USB module can't work, it requires 48MHz to work.
2. SSPI clock frequency is divide by two.

TEST=1. uart, i2c, timer, and pd modules are function normally
at different PLL frequency settings.
2. use 'flashrom' utility to flash EC binary with different
PLL settings.

1. To enable INT_PRI (hardware interrupt priority level 0~3)
register, bit0@INT_CTRL = 0.
2. GIE need to be enabled before UART is initialized.
[symptom]
To define CONFIG_RWSIG / CONFIG_RSA / CONFIG_SHA256, then power on:
after RW image is verified, firmware stuck in uart_flush_output().
