Subject: [PATCH] phy: rockchip-emmc: emmc_phy_init() always return 0

rockchip_emmc_phy_init() return variable is not set with the error value
if clk_get() failed. The debug message print 0 on error and the function
always return 0.
Fix it using PTR_ERR().

Fixes: 52c0624a10cce phy: rockchip-emmc: Set phyctrl_frqsel based on card clock
