Ake Koomsin c939a7c7b9 target/arm: honor HCR_E2H and HCR_TGE in arm_excp_unmasked() 
An exception targeting EL2 from lower EL is actually maskable when
HCR_E2H and HCR_TGE are both set. This applies to both secure and
non-secure Security state.

We can remove the conditions that try to suppress masking of
interrupts when we are Secure and the exception targets EL2 and
Secure EL2 is disabled.  This is OK because in that situation
arm_phys_excp_target_el() will never return 2 as the target EL.  The
'not if secure' check in this function was originally written before
arm_hcr_el2_eff(), and back then the target EL returned by
arm_phys_excp_target_el() could be 2 even if we were in Secure
EL0/EL1; but it is no longer needed.
