tpm_tis_spi: Remove limitation of transfers to MAX_SPI_FRAMESIZE bytes

Browse source

Limiting transfers to MAX_SPI_FRAMESIZE was not expected by the upper
layers, as tpm_tis has no such limitation. Add a loop to hide that
limitation.

v2: Moved scope of spi_message to the top as requested by Jarkko
