41fb5d46 : ArmPkg/ArmGic: Use the GIC Redistributor instead of GIC Distributor for GICv3
The changes to ArmGicIsInterruptEnabled() introduced the error where the Boolean
result is assigned to Interrupts, but then the bit position check is performed
again (against the computed Boolean result instead of the interrupt mask) during
the return statement.
Fix removes erroneous test and relies on boolean test made at return.

We never run any code at EL0, and so it would seem that any access
permissions set for EL0 (via the AP[1] attribute in the page tables) are
irrelevant. We currently set EL0 and EL1 permissions to the same value
arbitrarily.
However, this causes problems on hardware like the Apple M1 running the
MacOS hypervisor framework, which enters EL1 with SCTLR_EL1.SPAN
enabled, causing the Privileged Access Never (PAN) feature to be enabled
on any exception taken to EL1, including the IRQ exceptions that handle
our timer interrupt. When PAN is enabled, EL1 has no access to any
mappings that are also accessible to EL0, causing the firmware to crash
if it attempts to access such a mapping.
Even though it is debatable whether or not SCTLR_EL1.SPAN should be
disabled at entry or whether the firmware should put all UNKNOWN bits in
all system registers in a consistent state (which it should), using EL0
permissions serves no purpose whatsoever so let's fix that regardless.

Currently, at ExitBootServices() time, the GICv3 driver signals
End-Of-Interrupt (EOI) on all interrupt lines that are supported by the
interrupt controller. This appears to have been carried over from the
GICv2 version, but has been turned into something that violates the GIC
spec, and may trigger SError exceptions on some implementations.
Marc puts it as follows:
The GIC interrupt state machine is pretty strict. An interrupt can
only be deactivated (with or without prior priority drop) if it has
been acknowledged first. In GIC speak, this means that only the
following sequences are valid:
With EOImode==0:
x = ICC_IAR{0,1}_EL1;
ICC_EOIR{0,1}_EL1 = x;
With EOImode==1:
x = ICC_IAR{0,1}_EL1;
ICC_EOIR{0,1}_EL1 = x;
ICC_DIR_EL1 = x;
Any write to ICC_EOIR{0,1}_EL1 that isn't the direct consequence of
the same value being read from ICC_IAR{0,1}_EL1, and with the correct
nesting, breaks the state machine and leads to unpredictable results
that affects *all* interrupts in the system (most likely, the priority
system is dead). See Figure 4-3 ("Interrupt handling state machine")
in Arm IHI 0069F for a description of the acceptable transitions.
Additionally, on implementations that have ICC_CTLR_EL1.SEIS==1, a
SError may be generated to signal the error. See the various
<quote>
IMPLEMENTATION_DEFINED "SError ....";
</quote>
that are all over the pseudocode contained in the same architecture
spec. Needless to say, this is pretty final for any SW that would do
silly things on such implementations (which do exist).
Given that in our implementation, every signalled interrupt is acked,
handled and EOId in sequence, there is no reason to EOI all interrupts
at ExitBootServices() time in the first place, so let's just drop this
code. This fixes an issue reported by Marc where an SError is triggered
by this code, bringing down the system.

ITLinesNumber field in the GICD_TYPER register. The total number of
