This outer cache allows to control active ways independently for
each CPU, so this function will be useful to set up active ways
for a specific CPU.

but also as locked SRAM. The functions for turning on/off it
is necessary whether the L2 cache is enabled or not.

The UniPhier outer cache (L2 cache on ARMv7 SoCs) can be used as
SRAM by locking ways.
These functions will be used to transfer the trampoline code for SMP
into the locked SRAM.
