Subject: [PATCH v2] arm64: defconfig: Enable i.MX95 drivers for pinctrl,
 Ethernet and PCIe

From: João Paulo Gonçalves <joao.goncalves@...adex.com>

Enable i.MX95 pinctrl driver necessary for booting. Also enable the
missing drivers required for Ethernet and PCIe functionality. These
drivers are used on i.MX95 boards, including the NXP i.MX95 19x19 EVK.

The below configurations were enabled (listed with their DT nodes on
imx95.dtsi):

* CONFIG_PINCTRL_IMX_SCMI for the `scmi_iomuxc` pinctrl.
* CONFIG_CLK_IMX95_BLK_CTL for the HSIO domain clock controller
  (`hsio_blk_ctl`) used by the PCIe controller.
* CONFIG_NXP_NETC_BLK_CTRL for the NETC hardware domain controller
  (`netc_blk_ctrl`).
* CONFIG_NXP_ENETC4 for the Ethernet controller (`enetc_port*`).

Changes in v2:
- Rephrase the commit message to clearly explain why these configs were
  enabled and on which boards they are used.
- Link to v1:
