Subject: [PATCH v2 0/3] spi-nor: add optional vcc-supply and enable it for
 i.MX93

spi-nor flash needs power supply to work properly, the power supply
could be software controlled. So need enable the power before using the
flash.

Patch 1,2 is to add vcc-supply for spi-nor
Patch 3 is to add overlays for i.MX93-11x11-EVK

Changes in v2:
- Add A-b for patch 1, typo in patch 1
- Use devm_regulator_get_enable in patch 2
  I still keep it in spi_nor_scan because it is in probe stage.
- Link to v1: https://lore.kernel.org/r/20240920-spi-v1-0-97f220c2e10c@nxp.com
