ARM: i.MX8MM: add support for 8MMINILPD4-CPU2 board
This commit adds support for the 8MMINILPD4-CPU2 board. This board
replaced the ROHM BD71847 by the NXP PCA9450. The pbl PMIC configuration
is taken from upstream u-boot v2023.01.
[m.felsch@pengutronix.de: Fix pmic configuration settings to align with u-boot]
[m.felsch@pengutronix.de: Add dedicated dts support]
[m.felsch@pengutronix.de: Include Ahmad's review feedback]
