[PATCH 01/27] arm_mpam: Move MPAMF_ECR write helpers to allow reuse

[James Morse <james.morse@arm.com>]

From: Ben Horgan <ben.horgan@arm.com>

In preparation for calling mpam_enable_msc_ecr() from the CPU hotplug
handlers move it higher in the file. Move mpam_disable_msc_ecr() too to
keep them together.
