i.MX8MN LPDDR4 EVK board shares most of the device as DDR4 EVK board,
the ONLY difference are the DDR type and PMIC, add support for it
and make it default i.MX8MN EVK board as usual.
The PMIC driver is NOT ready, so cpu-freq needs to be disabled as
it depends on regulator provided by PMIC.

In order to maximise performance of the LCD Controller's 64-bit AXI
bus, for any give speed bin of the device, the AXI master interface
clock(ACLK) clock can be up to CPU_frequency/2, which is already
capable of optimal performance. In general, ACLK is always expected
to be equal to CPU_frequency/2. APB slave interface clock(PCLK) and
Main processing clock(PCLK) both are tied to the same clock as ACLK.
This change followed the LS1028A Architecture Specification Manual.
