Add an exception to bypass the read-only check for the SDAM02 reboot mode peripheral (slave_id=0, pid=0x71) in the SPMI write function. This peripheral needs to be writable to store reboot reason information, even when the channel is marked as read-only due to ownership by a different execution environment. The change adds: - SDAM02_REBOOT_MODE_PID definition (0x71) - Runtime check in msm_spmi_write() to skip read-only enforcement for this specific peripheral This allows the reboot mode to be written successfully while maintaining read-only protection for all other peripherals.
