xen: fixes and cleanups for 5.4-rc2

It contains the following patches:

- a fix in the Xen balloon driver avoiding hitting a BUG_ON() in some
  cases, plus a follow-on cleanup series for that driver

- a patch for introducing non-blocking EFI callbacks in Xen's EFI driver,
  plu a cleanup patch for Xen EFI handling merging the x86 and ARM arch
  specific initialization into the Xen EFI driver

- a fix of the Xen xenbus driver avoiding a self-deadlock when cleaning
  up after a user process has died

- a fix for Xen on ARM after removal of ZONE_DMA

- a cleanup patch for avoiding build warnings for Xen on ARM


Thanks.

Juergen
