clk: samsung: clk-pll: Add support for pll_1418x

pll1418x is used in Exynos7885 SoC for USB PHY clock.
Operation-wise it is very similar to pll0822x, except that MDIV is only
9 bits wide instead of 10, and we use the CON1 register in the PLL
macro's "con" parameter instead of CON3 like this:

	PLL(pll_1418x, CLK_FOUT_USB_PLL, "fout_usb_pll", "oscclk",
	    PLL_LOCKTIME_PLL_USB, PLL_CON0_PLL_USB,
	    pll_usb_rate_table),

Technically the PLL should work fine with pll0822x code if the PLL
tables are correct, but it's more "correct" to actually update the mask.
