rockchip/rk3399: Fix rkclk_init() to actually use PERILP1_PCLK_HZ
This patch fixes a typo in the clock initialization code that caused the
PERILP1_PCLK_HZ constant to be ignored and the clock to always run at
the same speed as its parent (PERILP1_HCLK_HZ). Since we've done all our
previous tests and validation with this bug, we should probably increase
the value of the constant (that had not actually been used) to the value
that we had been incorrectly using instead (which also makes effective
SPI read times faster).
BRANCH=None
BUG=chrome-os-partner:56556
TEST=Booted Kevin.
