clk: samsung: clk-pll: Add support for pll_{1051x,1052x}

These plls are found in the Exynos8895 SoC:
- pll1051x: Integer PLL with middle frequency
- pll1052x: Integer PLL with low frequency

The PLLs are similar enough to pll_0822x, so the same code can handle
all.

Locktime for 1051x, 1052x is 150 - the same as the pll_0822x
lock factor. MDIV, SDIV, PDIV masks and bit shifts are also the same
as 0822x.

When defining a PLL, the "con" parameter should be set to CON0
register, like this:

PLL(pll_1051x, CLK_FOUT_SHARED0_PLL, "fout_shared0_pll", "oscclk",
    PLL_LOCKTIME_PLL_SHARED0, PLL_CON0_PLL_SHARED0,
    pll_shared0_rate_table),
