[U-Boot] [UBOOT PATCH 1/4] armv7: psci: make v7_flush_dcache_all public for all psci code

[macro.wave.z at gmail.com]

From: Hongbo Zhang <hongbo.zhang at nxp.com>

The v7_flush_dcache_all function will be called by ls102xa platform system
suspend, it is necessary to make it a public call instead of a local one, but
changing the LENTRY to ENTRY isn't enough, because there is another one using
the same name, so this one gets a psci_ prefix.
