octeontx: add linux 5.10 testing kernel support

Browse Source 
Changes from 5.4 to 5.10:
-------------------------
 - patches from 5.4 are all upstream for 5.10 execpt for
   0004-PCI-add-quirk-for-Gateworks-PLX-PEX860x-switch-with-.patch

 - disable block device data integrity (DIF/DIX/T10) in default config
   (CONFIG_BLK_DEV_INTEGRITY)
   This feature is only supported by:
     - Enterprise SAS/SCSI HBAs and Disks
     - Software raid
     - NVMEs with metadata capabilities (most don't have this)
   None of which are part of any octeontx boards.

 - arm64 TEXT_OFFSET (0x80000) has been removed after 5.4
   This will break Uimages with kernel load addresses that aren't 2MiB
   aligned any longer. Resulting in the kernel silently fail to boot.
   For Gatworks newport boards for example, the uimage kernel load
   and execute address is 0x20080000. These need to be changed to
   0x20000000 when running kernels beyond 5.4.

Tested-on: Gateworks Newport GW64xx
