Vadim Bendebury 6b24cff09b tpm: allow TPM_FW_VER register to return arbitrary number of bytes ...

As the version string grows longer, reading it in 4 byte chunks
becomes more and more expensive, the overhead of setting up a separate
SPI transaction per very chunk is just too much.

There is no reason not to allow the host to read as many bytes at a
time as it requires (limiting it by the maximum version string buffer
size of course).

BRANCH=none
BUG=chrome-os-partner:55558
TEST=verified that the version string is still read properly by the
     TPM driver on Kevin
