Subject: [PATCH 5.4 44/60] clk: sunxi-ng: mp: fix parent rate change flag check

From: Jernej Skrabec <jernej.skrabec@...l.net>

[ Upstream commit 245090ab2636c0869527ce563afbfb8aff29e825 ]

CLK_SET_RATE_PARENT flag is checked on parent clock instead of current
one. Fix that.

Fixes: 3f790433c3cb ("clk: sunxi-ng: Adjust MP clock parent rate when allowed")
