[PATCH RESEND] arm64: meson: select COMMON_CLK

[PATCH RESEND] arm64: meson: select COMMON_CLK

[Jerome Brunet]

This fix the recent removal of clock drivers selection.
While it is not necessary to select the clock drivers themselves, we need
to select a proper implementation of the clock API, which for the meson, is
CCF

note to self: ARCH_MULTIPLATFORM for the 32-bit SoCs also selects this

Why is this needed, and why would this make any difference?
COMMON_CLK is always enabled on arm64, as the main ARM64 symbol in
arch/arm64/Kconfig selects it.

Ah indeed. Shortly after commit ba66a25536dd was merged I remember I had
problem with COMMON_CLK (or any other clock implementation) being
selected. TBH, I don't remember it exactly ...

For sure this was a mistake.
Neil, can you still drop it and do you need a revert ?

I can't drop it, it has already been merged.

Please send a revert and I'll push it for 5.14-rc fixes.
