Subject: [PATCH 08/13] arm64: defconfig: Enable CR50 TPMs

Enable support for the CR50 TPMs present on Chromebooks. They can be
connected through SPI or I2C, and there's a different driver for each
case, so enable both.

By enabling this on the defconfig we make it effortless to test the
relevant hardware on CI systems like KernelCI.
