fix(stm32mp1_clk): fix MCU/AXI parent clock

Correct MCU clock parent selector: MCU subsystem clock is derived
from clock  PLL3_P, not PLL3.

Correct AXI clock parent selector: AXI subsystem clock is derived
from clock  PLL2_P, not PLL2.

This change also renames MCU clock and AXI clock resources to
prevent confusion.
