[PATCH v3 0/2] tpm: add optional max xfer size check

[Andrey Pronin <apronin-F7+t8E8rja9g9hUCZPvPmw@public.gmane.org>]

This patchset introduces an optional maximum transfer size that can
be specified by a tpm driver. Setting the max_xfer_size helps to catch
the cases when burstcnt is incorrectly reported by the device (e.g. >64
for spi - happened in practice) and gracefully handle such situations.

v2: removed unnecessary accessors in tpm_tis_core.h, fixed style

v3: simplified logic: simply cap the burstcnt at max_xfer_size, don't
attempt to re-request from tpm.
