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.
