[PATCH 5/5] remoteproc: imx_rproc: set address of .interrupts section as bootaddr

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

i.MX93 M33 has ROM, it needs the ".interrupts" section address to start
M33 firmware. In current design, the Arm Trusted Firmware(ATF) use TCML
start address when the 2nd arg is 0 when SMC call. So When the M33 firmware
is built with TCML address, it works well.

However when M33 firmware is built to run in DDR, we need pass the
".interrupts" address as 2nd arg to ATF to start M33 firmwrae.
