build_kernel_image: Configure tpm_tis command line override per platform
A boot warning similar to the following is seen on many platforms.
tpm tpm0: tpm_try_transmit: tpm_send: error -5
tpm tpm0: tpm_relinquish_locality: : error -1
tpm_tis: probe of tpm_tis failed with error -5
The error is more severe on some other platforms. On lars, we see
the following warning and traceback:
------------[ cut here ]------------

This is due to the "tpm_tis.force=1 tpm_tis.interrupts=0" command line
flags, which are currently provided for all platforms in the generic
build_kernel_image.sh. Unfortunately, some older platforms do need those
flags, so they can not be removed entirely. Move the flags to per-platform
build scripts where needed to solve the problem.
