[PULL 78/79] ARM: hyp-stub: Fix Thumb-2 compilation

From: Marc Zyngier <marc.zyngier at arm.com>

The assembler defaults to emiting the short form of ADR, leading
to an out-of-range immediate. Using the wide version solves this
issue.

Fixes: bc845e4fbbbb ("ARM: KVM: Implement HVC_RESET_VECTORS stub hypercall in the init code")
