clk: mdss: remove configuring phy registers during pll disable
DSI driver needs to disable pll and enable clamps before entering into
low power state. Since the PLL disable is configuring GLBL_TEST_CNTRL,
CLK_BUF PHY registers to 0, these registers are not restored after the
clamps are disabled. This change avoids configuring these registers
during PLL disable and gets disabled during dsi off.
