BACKPORT: tpm: Enable CLKRUN protocol for Braswell systems
To overcome a hardware limitation on Intel Braswell systems,
disable CLKRUN protocol during TPM transactions and re-enable
once the transaction is completed.
Conflicts:
- Due to not picking
("00194826e6be tpm_tis: Clean up the force=1 module parameter")
Since the 'force' parameter is enabled for 3.18 kernel,
pnp_register_driver() doesn't get called. Hence had to move
the ioremap()/iounmap() calls into the functions
init_tis()/cleanup_tis() respectively.
- Not adding the intel-family.h file from
("970442c599b2 x86/cpu/intel: Introduce macros for
Intel family numbers") for adding a single
macro. Instead explicitly defined INTEL_FAM6_ATOM_AIRMONT.
