Implement ehi flag ATA_EHI_PRINTINFO. This flag is set when device
configuration needs to print out device info. This used to be handled
by @print_info argument to ata_dev_configure() but LLDs also need to
know about it in ->dev_config() callback.
This patch replaces @print_info w/ ATA_EHI_PRINTINFO and make sata_sil
print workaround messages only on the initial configuration.
