ARM: dts: Add mask-tpm-reset node in exynos5800-peach-pi
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.
