Lukas Wunner 23595de568 dt-bindings: tpm: Add compatible string atmel,attpm20p
Commit 4f2a348aa3 ("arm64: dts: imx8mm-venice-gw73xx: add TPM device")
added a devicetree node for the Trusted Platform Module on certain
Gateworks boards.

The commit only used the generic "tcg,tpm_tis-spi" compatible string,
but public documentation shows that the chip is an ATTPM20P from Atmel
(nowadays Microchip):
https://trac.gateworks.com/wiki/tpm

Add the chip to the supported compatible strings of the TPM TIS SPI
schema.

For reference, a datasheet is available at:
