remoteproc updates for v5.7

Browse source 
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.
