The mask-tpm-reset GPIO is used by the kernel to prevent the TPM from
being reset across sleep/wake. If we don't set it to anything then
the TPM will be reset. U-Boot will detect this as invalid
and will reset the system on resume time. This GPIO can always be low
and not hurt anything. It will get pulled back high again during a
normal warm reset when it will default back to an input.
To properly preserve the TPM state across suspend/resume and to make
the chrome U-Boot happy, properly set the GPIO to mask the
reset to the TPM.

Looks good to me. I'll assume Kukjin will add the words
"exynos5420-peach-pit" into the patch description when applying.
Yes :)
