Jarkko Sakkinen 7cd46930b8 tpm: Prevent hwrng from activating during resume 
[ Upstream commit 99d46450625590d410f86fe4660a5eff7d3b8343 ]

Set TPM_CHIP_FLAG_SUSPENDED in tpm_pm_suspend() and reset in
tpm_pm_resume(). While the flag is set, tpm_hwrng() gives back zero
bytes. This prevents hwrng from racing during resume.
