[GIT PULL] irqchip updates for 4.20

[Marc Zyngier <marc.zyngier@arm.com>]

Hi Thomas,

Here's the set of irqchip updates for 4.20. On the menu this time,
support for the Marvell SEI and Cirrus Logic Madera interrupt
controllers, support for kexec on GICv3 system, as well as a few
fixes and cleanups.

Note that the GICv3/kexec stuff depends on some EFI updates. The whole
branch is thus based on tip/efi/irqchip which Ingo has created for
this purpose.

Please pull,

       M.

The following changes since commit a23d3bb05ccbd815c79293d2207fedede0b3515d:

  efi: add API to reserve memory persistently across kexec reboot (2018-09-26 12:03:57 +0200)
