Subject: [PATCH v10 09/27] drivers: firmware: psci: Move psci to separate directory

Some following changes extends the PSCI driver with some additional new
files.  Let's avoid to continue cluttering the toplevel firmware directory
and first move the PSCI files into a PSCI sub-directory.

Suggested-by: Mark Rutland <mark.rutland@....com>
Signed-off-by: Ulf Hansson <ulf.hansson@...aro.org>
