phy: exynos5-usbdrd: fix MPLL_MULTIPLIER and SSC_REFCLKSEL masks in refclk 

stable inclusion
from stable-v6.6.81
commit 4bddfde8b692d6e07021607236efbc2c2e9f0d0d
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBYZED

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=4bddfde8b692d6e07021607236efbc2c2e9f0d0d



--------------------------------

commit e2158c953c973adb49383ddea2504faf08d375b7 upstream.

In exynos5_usbdrd_{pipe3,utmi}_set_refclk(), the masks
PHYCLKRST_MPLL_MULTIPLIER_MASK and PHYCLKRST_SSC_REFCLKSEL_MASK are not
inverted when applied to the register values. Fix it.
