[PATCH v8 10/11] pmdomain: imx93-blk-ctrl: mask DSI and PXP PD domain register on i.MX91

[Joy Zou <joy.zou@nxp.com>]

The i.MX91 is derived from i.MX93, but there is no DSI and PXP in i.MX91,
Add skip_mask in struct imx93_blk_ctrl_data, then skip DSI and PXP for
i.MX91 Soc.

Changes for v8:
1. modify commit message.

Changes for v7:
1. Optimize i.MX91 num_clks hardcode with ARRAY_SIZE().

Changes for v5:
1. The i.MX91 has different PD domain compared to i.MX93,
   so add new imx91 dev_data.
