[PATCH 1/3] clk: stm32mp1: add i2s_ckin as a clock source of PLL4

[Gabriel Fernandez]

The PLL4SRC field of RCC_RCK4SELR selects the PLL4 reference clock
among HSI, HSE, CSI and I2S_CKIN. The driver only lists the first three
as parents of PLL4.

Add "i2s_ckin" to the PLL4 parents. This clock name is already used as
a parent by other clocks of this driver (I2S/SAI/SPDIF kernel clocks)
and is expected to be provided by the board device tree.
