[PATCH] ARM: i.MX93: tqm93xx: add PMIC node

The PMIC is needs to be configured on the tqm93xx to properly reset the
board, see the board specific initialisation code. We had a PMIC node
in our downstream dts file which we dropped in favour for using the
upstream dts. The upstream dts doesn't have a PMIC node yet, so add it
again. We do not need the regulator subnodes though, as barebox doesn't
support them anyway.
