[PATCH v3 1/1] phy: freescale: limit div value in FIELD_PREP()

[Chongchong Gu]

From: guchongchong <guchongchong at xiaomi.com>

In fsl_samsung_hdmi_phy_configure_pll_lock_det, the variable named
div becomes 4 after loop. It must less than 4 in function named
FIELD_PREP(REG12_CK_DIV_MASK, div).

A way to reproduce when run the following shell command
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j4
