Subject: [PATCH AUTOSEL 5.6 26/68] clocksource/drivers/timer-microchip-pit64b: Fix rate for gck

From: Claudiu Beznea <claudiu.beznea@...rochip.com>

[ Upstream commit 0585244523f0f4de7e4480375e871617a79cab98 ]

Generic clock rate needs to be set in case it was selected as timer clock
source in mchp_pit64b_init_mode(). Otherwise it will be enabled with wrong
rate.
