[RESEND PATCH 0/2 v6] Add AXS10X I2S PLL clock driver

The ARC SDP I2S clock can be programmed using a specific PLL. This patch series has the goal of adding a clock driver that programs this PLL. Changes v5 -> v6: * Use parent clock to determine PLL input rate instead of using hardcoded values * Documentation update (added 'clocks' field) * De
