This check has been obsolete since commit c51f02cf14
("include:
sbi_platform: Introduce HART index to HART id table"). It originally
filtered out harts that were disabled in the FDT, but those harts are
omitted from the hart_index2id table, so they will hang in fw_base.S
after the "Find HART index" loop and never enter sbi_init().
