[PATCH] arm64: dts: imx8m*-venice-gw7: Fix TPM schema violations

[PATCH] arm64: dts: imx8m*-venice-gw7: Fix TPM schema violations

[Tim Harvey]

Since commit 26c9d152ebf3 ("dt-bindings: tpm: Consolidate TCG TIS
bindings"), several issues are reported by "make dtbs_check" for arm64
devicetrees:

The compatible property needs to contain the chip's name in addition to
the generic "tcg,tpm_tis-spi".

tpm@1: compatible: ['tcg,tpm_tis-spi'] is too short
	from schema $id:
http://devicetree.org/schemas/tpm/tcg,tpm_tis-spi.yaml#

Fix these schema violations.

Gateworks Venice uses an Atmel ATTPM20P:
