  arm-common: gic-v3: Mark last CPUs GICR as last

There are scenarios where Linux boots up with less number of cores
than the SoC supports. In such cases, finding GICR region marked with
GICR_TYPER_Last is not possible for any non-root cell. This is
because hypervisor gives an unhandled trap to any access of GICR
region that does not correspond to system CPU set.

Fix this by emulating GICR region as last that corresponds to the
last available CPU in the system CPU set.

  tools: cell-linux: Add support for compressed arm64 kernel images

The arm64 Linux boot protocol allows compressed images but they have to
be decompressed by the bootloader, and that's jailhouse-cell-linux in
our case. Detect those images by trying to decompress them and use the
decompressed version from then on.

  inmates: arm: fix broken heartbeat

Since 9675814c6fe3e6 ("arm/arm64: Reject hypercalls with wrong immediate
code"), Jailhouse rejects all HVCs with immediate codes other than
0x4a48.

This breaks the assumption that the heartbeat() pseudo HVC makes on all
ARM platforms.

We must provide 0x4a48 as immediate code, but use an invalid function
argument in order to return to our cell. 0xdeadbeef sounds reasonable.

Let's use this cance to consolidate arm and arm64 code and use our
common jailhouse_call interface.
