[PATCH v2 2/3] clk: samsung: clk-pll: Add support for pll_309

[Aiden Isik via B4 Relay]

From: Aiden Isik <aidenisik@xxxxxxxxxxxxxx>

pll_309 (referred to in the downstream kernel sources as frd_309_rpll) is
one of two PLLs used in the Exynos5515 SoC. It is an integer/fractional
PLL with an FVCO of 600-2400MHz.

It has the same locktime (500), and kdiv/mdiv/pdiv/sdiv masks and shifts
as pll_531x, so it can be handled in exactly the same way.

When defining a PLL, the "con" parameter should be set to the CON3
register, like this:

PLL(pll_309, CLK_FOUT_AUD_PLL, "fout_aud_pll", "oscclk",
    PLL_LOCKTIME_PLL_AUD, PLL_CON3_PLL_AUD, NULL),
