Add i.MX8MM ccf driver support.
Modifed from Linux Kernel 5.3.0-rc1, drop some entries
that not used in U-Boot and adapt to U-Boot CCF style.

This patch brings the files from Linux kernel (linux-stable/linux-5.1.y
SHA1: 5752b50477da)to provide clocks support as it is used on the Linux
kernel with Common Clock Framework [CCF] setup.
The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the
device tree.
One needs to pay attention to the comments indicating necessary for U-Boot's
driver model changes.
If needed, the code can be extended to support the "set" part of the clock
management.

Add clk driver for i.MX8QXP. This basic version supports clk
enable/disable/get_rate/set_rate operations for I2C, ENET,
SDHC0 and UART clocks.
