MLK-16564-02 dts: imx7ulp-evk: add rpmsg gpio PTA and PTB support
Add rpmsg gpio PTA and PTB support.
Since currently M4 image support dynamical channel allocation,
and reserve below memory for kernel service and app channel:
* --0x9FF00000~0x9FF0FFFF: pmic,pm,audio,keys,gpio
* --0x9FF10000~0x9FF1FFFF: pingpong,virtual tty
Change the rpmsg instances of A core part to sync with M core.
Test M4 image built from Wayne Feng, M4 image commit ID: b1321d4aca82
