From: Vitor Soares <vitor.soares@xxxxxxxxxxx>
Add TPM device found on Verdin iMX8M Mini PID4 0090 variant.
While adding the node, rename `pinctrl_pmic_tpm_ena` to
`pinctrl_tpm_spi_cs`.
Signed-off-by: Vitor Soares <vitor.soares@xxxxxxxxxxx>

v2->v3
- Match node name with label `pinctrl_tpm_spi_cs`.
v1->v2
- rename `pinctrl_pmic_tpm_ena` to `pinctrl_tpm_spi_cs`.
