Jarkko SakkinenandGreg Kroah-Hartman 7cd46930b8 tpm: Prevent hwrng from activating during resume

[ Upstream commit 99d4645062 ]

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.
