Claudiu Beznea c10e3c919a clk: at91: clk-main: update key before writing AT91_CKGR_MOR
[ Upstream commit 85d071e7f1 ]

SAMA5D2 datasheet specifies on chapter 33.22.8 (PMC Clock Generator
Main Oscillator Register) that writing any value other than
0x37 on KEY field aborts the write operation. Use the key when
selecting main clock parent.

Fixes: 27cb1c2083 ("clk: at91: rework main clk implementation")
