arm64: dts: Fix TPM schema violations

Since commit 26c9d152

 ("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" and the nodename needs to be "tpm@0"
rather than "cr50@0":

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

  cr50@0: $nodename:0: 'cr50@0' does not match '^tpm(@[0-9a-f]+)?$'
        from schema $id: http://devicetree.org/schemas/tpm/google,cr50.yaml#

Fix these schema violations.
