arm64: Expand SMCCC arguments and return values

PSCI uses the SMC Calling Convention (SMCCC) to communicate with the higher
level software. PSCI uses at most 4 arguments and expend only one return
value. However, SMCCC has provisions for more arguments (upto 17 depending
on the SMCCC version) and upto 10 distinct return values.

We are going to be adding tests that make use of it, so add support for the
extended number of arguments and return values.

Also rename the SMCCC functions to generic, non-PSCI names, so they
can be used for Realm services.

arm/arm64: target-efi prep

This series mostly prepares kvm-unit-tests/arm for targeting EFI
platforms. The actually EFI support will come in another series,
but these patches are good for removing assumptions from our memory
maps and about our PSCI conduit, even if we never merge EFI support.

arm/arm64: psci: Don't assume method is hvc

The method can be smc in addition to hvc, and it will be when running
on bare metal. Additionally, we move the invocations to assembly so
we don't have to rely on compiler assumptions. We also fix the
prototype of psci_invoke. function_id should be an unsigned int, not
an unsigned long.

lib: arm: Implement PSCI SYSTEM_OFF in psci_system_off()

A new function, psci_system_off(), is added which implements the PSCI
SYSTEM_OFF function. A call causes the hypervisor to terminate the virtual
machine.

We take this opportunity to rename psci_sys_reset() to psci_system_reset()
to match the name of the PSCI function SYSTEM_RESET that it implements.

Consumers for the function will be added in a later patch.

lib: add linux dir for kernel uapi headers

We needed to import some uapi headers, e.g. lib/arm/asm/uapi-psci.h,
and will need some others, e.g. pci_regs.h, in the future. Create a
linux directory for them in lib so that they can be included with
the familiar <linux/header.h> reference.

(Note, x86 has been cheating. lib/x86/pci.c already includes
<linux/pci_regs.h>, which it's been getting away with as its include
paths are less strict than arm's, i.e. it *does* look in /usr/include)
