if cpu_gpr_d[r3] == 0 then we were shifting the lower register to the
right by 32 which is undefined behaviour. In this case the TriCore would
do nothing an just return the higher register cpu_reg_d[r1]. We fixed
that by detecting whether cpu_gpr_d[r3] was zero and cleared the lower

This series contains some random trivial cleanups I came across when working on
the PC machines. It consists of reducing the usage of global variables and
eliminating some redundancies.
Testing done:
* `make check`
* `qemu-system-x86_64 -M q35 -m 2G -cdrom \
The variable is redundant to "phb" and is never used by its real type.

When confidential-guest-support is enabled for the virt machine, call
the RME init function, and add the RME flag to the VM type.
* The Realm differentiates non-secure from realm memory using the upper

A realm cannot be reset, it must be recreated from scratch. The RMM
specification defines states of a Realm as NEW -> ACTIVE -> SYSTEM_OFF,
after which the Realm can only be destroyed. A PCSI_SYSTEM_RESET call,
which normally reboots the system, puts the Realm in SYSTEM_OFF state.
QEMU does not
The machine code calls kvm_arm_rme_vm_type() to get the VM flag and
kvm_arm_rme_init() to issue KVM hypercalls in the required order:
* create the realm descriptor early,
* finalize the REC (vCPU) after the registers are reset,
* load images into Realm RAM (in another patch),
* activate the realm
The confidential guest support in KVM limits the number of registers
that we can read and write. Split the get/put_registers function to
prepare for it.

Mark up the sysreg definitions for the registers trapped
by HDFGRTR/HDFGWTR bits 12..x.
Bits 12..22 and bit 58 are for PMU registers.
The remaining bits in HDFGRTR/HDFGWTR are for traps on
registers that are part of features we don't implement:
Bits 23..32 and 63 : FEAT_SPE
Bits 33..48 :
Mark up the sysreg definitions for the registers trapped
by HFGRTR/HFGWTR bits 36..63.
Of these, some correspond to RAS registers which we implement as
always-UNDEF: these don't need any extra handling for FGT because the
UNDEF-to-EL1 always takes priority over any theoretical
FGT-trap-to-EL2.
Mark up the sysreg definitions for the system instructions
trapped by HFGITR bits 12..17. These bits cover AT address
translation instructions.

The AArch32 ATS12NSO* address translation operations are supposed to
trap to either EL2 or EL3 if they're executed at Secure EL1 (which
can only happen if EL3 is AArch64). We implement this, but we got
the syndrome value wrong: like other traps to EL2 or EL3 on an
AArch32 cpreg access, they
The encodings 0,0,C7,C9,0 and 0,0,C7,C9,1 are AT SP1E1RP and AT
S1E1WP, but our ARMCPRegInfo definitions for them incorrectly name
them AT S1E1R and AT S1E1W (which are entirely different
instructions). Fix the names.
(This has no guest-visible effect as the names are for debug purposes
only.)
