Alexander Sverdlin f3b70b6e33 tpm: tis_i2c: Limit read bursts to I2C_SMBUS_BLOCK_MAX (32) bytes 
Underlying I2C bus drivers not always support longer transfers and
imx-lpi2c for instance doesn't. SLB 9673 offers 427-bytes packets.

Visible symptoms are:

tpm tpm0: Error left over data
tpm tpm0: tpm_transmit: tpm_recv: error -5
tpm_tis_i2c: probe of 1-002e failed with error -5
