Nowdays, there are more and more requirements of building SoC specific drivers as
modules, such as Android GKI (generic kernel image), this patch set supports building
i.MX ARMv8 SoCs clock drivers as modules,

The CLK_IMXxxx is introduced for i.MX ARMv7 platforms in order to make the build options
aligned, the reason why i.MX ARMv7 platforms clock driver do NOT support module build
and COMPILE_TEST is because, some drivers like i.MX GPT timer driver depends on clock
driver to be ready before it, GPT driver uses TIMER_OF_DECLARE(), while i.MX6/7 clock
drivers use CLK_OF_DECLARE(), and GPT driver is critical for i.MX6/7 platforms kernel
boot up, so GPT driver needs to be changed to support loadable clock driver first,
then the i.MX6/7 clock drivers can support loadable module, this will be done later.

Changes since V8:
	- explicitly include linux/bits.h in patch #1.

Anson Huang (6):
  clk: imx6sl: Use BIT(x) to avoid shifting signed 32-bit value by 31
    bits
  clk: composite: Export clk_hw_register_composite()
  clk: imx: Support building i.MX common clock driver as module
  clk: imx: Add clock configuration for ARMv7 platforms
  clk: imx8m: Support module build
  clk: imx8qxp: Support building i.MX8QXP clock driver as module

Use readl_relaxed() instead of __raw_readl(), and use BIT(x)
instead of (1 << X) to fix below build warning reported by kernel
test robot:

drivers/clk/imx/clk-imx6sl.c:149:49: warning: Shifting signed 32-bit
value by 31 bits is undefined behaviour [shiftTooManyBitsSigned]
     while (!(__raw_readl(anatop_base + PLL_ARM) & BM_PLL_ARM_LOCK))

There are more and more requirements of building SoC specific drivers
as modules, add support for building i.MX common clock driver as module
to meet the requirement.

Add CONFIG_CLK_xxx for i.MX ARMv7 platforms, and use it as build option
instead of CONFIG_SOC_xxx, the CONFIG_CLK_xxx will be selected by default
according to CONFIG_SOC_xxx.
