ARM: imx: Fix parsing of ROM log event IDs on iMX8M

It seems like the ROM log events for the iMX8M are not fully covered by
AN12853 i.MX ROMs Log Events, Rev. 0, May 2020. On iMX8M the ROM event
ID 0x82 seems to use parameter0 which stops the parsing because the end
of list is detected too early.

This patch adds ROM event ID 0x82 and skips the next word if ID 0x82 is
parsed.

Fixes: a5ee05cf71 ("ARM: imx: Pick correct eMMC boot partition from ROM log")
