Subject: [PATCH v3 1/8] riscv: dts: microchip: remove icicle memory clocks

From: Conor Dooley <[email protected]>

The clock properties in the icicle kit's memory entries cause dtbs_check
errors:
arch/riscv/boot/dts/microchip/microchip-mpfs-icicle-kit.dtb: /: memory@80000000: 'clocks' does not match any of the regexes: 'pinctrl-[0-9]+'

Get rid of the clocks to avoid the errors.

Reported-by: Palmer Dabbelt <[email protected]>
Fixes: 0fa6107eca41 ("RISC-V: Initial DTS for Microchip ICICLE board")
Fixes: 5b28df37d311 ("riscv: dts: microchip: update peripherals in icicle kit device tree")

I guess the memory controller consuming this clock will be sitting
somewhere in the io-area of the soc instead
