[RFC PATCH 3/4] firmware: arm_ffa: revert ffa_init() initcall level to device_initcall

[Yeoreum Yun]

commit 0e0546eabcd6 ("firmware: arm_ffa: Change initcall level of ffa_init() to rootfs_initcall")
changed the initcall level of ffa_init() to rootfs_initcall to address
an issue where IMA could not properly recognize the TPM device.

However, this introduces a problem: pKVM fails to handle any FF-A calls
because it cannot trap the FFA_VERSION call invoked by ffa_init().

Since the IMA init function level has been changed to late_initcall_sync,
there is no longer a need to keep ffa_init() at rootfs_initcall.
Revert it back to device_initcall.
