arm/hafnium: update to v2.8

Browse Source 
Update hafnium to v2.8, which allows updating tc1 to that version and
remove the intermediate SHA.  It also allows for the removal of some
backported patches.

From 1c4d28493faed6cf189c75fa91d19131e6a34e04 Mon Sep 17 00:00:00 2001
From: Olivier Deprez <olivier.deprez@arm.com>
Date: Mon, 8 Aug 2022 19:14:23 +0200
Subject: [PATCH] feat: disable alignment check for EL0 partitions
Relax hw alignment check specifically for (S-)EL0 partitions when
Hafnium runs with VHE enabled. EL1 partitions have a specific control
for EL1 and EL0 with respect to alignment check.
Create a hyp_state structure (from already defined flying registers)
within the vCPU context to hold the Hypervisor EL2 static configuration
applied when a vCPU runs. This state is switched back and forth when
running the Hypervisor or the VM.
Add SCTLR_EL2 to this context. An EL0 partition context is initialized
with SCTLR_EL2.A=0 such that alignment check is disabled when EL0 runs
in the EL2&0 translation regime. SCTLR_EL2.A is set back when returning
to the Hypervisor such that Hypervisor execution runs with aligment
check enabled at EL2.
Remove HCR_EL2 saving from vCPU exit path provided this register state
is static and doesn't change while a vCPU runs.
The rationale for such change is to permit running upstream SW stacks
such as the EDKII/StandaloneMm [1] for which default build assumes
unaligned accesses are permitted. Similar query exists for running
Trusted Services on top of Hafnium [2].
