[PATCH v5 0/3] clk: Add APM X-Gene SoC clock driver

[Loc Ho]

This patch adds APM X-Gene SoC clock driver support. Reference,
PCP PLL, SoC PCP, and Ethernet clocks are defined via the DTS.

-v5:
 * Remove duplicate code for soc/pcp clk init function
 * Remove un-used flags field from structure
 * Merge error handler code for device clock init function
 * Update binding documentation

-v4:
 * Remove flags from DTS and check status instead
 * Change DTS reg entry to be identified by reg-names property

-v3:
 * Make DTS compatible type for SoC PLL and PCP PLL
 * Make use of of_iomap instead direct ioremap call
 * Make kzalloc with variable instead structure
 * Remove DTS binding for fixed-clock and fixed_factor_clock
 * Remove unnecessary arch_initcall

-v2:
 * Make depends on ARM64
 * Fix duplicate registration

-v1 - Initial post
