ioex: Initialize IO expander for early sysjump
ioex: Initialize IO expander for early sysjump

When EFS triggers sysjump, IO expander is currently not initialized.

This patch will make IO expander initialized in RW if sysjump is
triggered by EFS.

IO expander initalization should be skipped only for late sysjump.
