[PATCH 0/2] arm64: remove generic ARM cpuidle support

[Michael Walle]

Playing with an own PSCI implementation, I've noticed that the cpuidle-arm
driver doesn't work on arm64. It doesn't probe because since commit
788961462f34 ("ARM: psci: cpuidle: Enable PSCI CPUidle driver") the
arm_cpuidle_init() can only return -EOPNOTSUPP, because the commit removed
the cpu_idle_init and cpu_suspend ops.

It left me puzzled for quite some time. It seems that the cpuidle-psci is
the preferred one and this has been the case for quite some time. The
mentioned commit first appeared in v5.4.

Remove the ARM64 support for the cpuidle-arm driver, which then let us
remove all the supporting arch code.
