i2c: exynos5: Add support for Exynos8895 SoC

Browse source

Exynos8895 functioning logic mostly follows I2C_TYPE_EXYNOS7, but timing
and temp calculations are slightly different according to the following
logic:

FPCLK / FI2C = (CLK_DIV + 1) * (TSCLK_L + TSCLK_H + 2) + 2 *
((FLT_CYCLE + 3) - (FLT_CYCLE + 3) % (CLK_DIV + 1))

temp := (FPCLK / FI2C) - (FLT_CYCLE + 3) * 2
