configs/ti_am62ax_sk_defconfig: Fix kernel configuration

Browse Source 
The k3-am62a7-sk.dts describes an I2C PMIC TPS659312 which features a
number of regulators. One of them, ldo1, is used as power supply for the
SD card host controller regulator. When the rootfs is on the SD
card (like with this configuration), we need support for these three
components (Regulator driver, I2C PMIC glue and PMIC MFD driver) to be
built-in in order to avoid boot failures.

Tested on an AM62A LP SK.
