remoteproc updates for v5.7

This introduces a range of improvements to the OMAP remoeteproc driver;
among other things adding devicetree, suspend/resume and watchdog
support, and adds support the remoteprocs in the DRA7xx SoC.

It introduces support for 64-bit firmware, extends the ELF loader to
support this and fixes for a number of race conditions in the recovery
handling.

It introduces a generic mechanism to allow remoteproc drivers to sync
state with remote processors during a panic, and uses this to prepare
Qualcomm remote processors for post mortem analysis.

Finally it introduces fixes to cleanly recover from crashes in the modem
firmware on production Qualcomm devices.
