[PATCH 3/5] clk: qcom: ipq4019: Added the cpu pll divider and changed regmap limit

[Abhishek Sahu <absahu@codeaurora.org>]

This patch adds the APSS CPU PLL divider in clock framework and
its binding in IPQ4019 device tree binding.

Also, it changed the max_register value to 0x2FFFF in regmap config
to support the APSS CPU PLL divider operations.
