fix(smmu): set root port CR0 GPCEN before ACCESSEN

In the SMMU root port programming model, changing both
SMMU_ROOT_CR0.GPCEN and ACCESSEN bits in the same MMIO write operation
is permitted by the architecture but left to the SMMU IP implementation
to determine the order of completing one or the other operation.

Enforce more determinism by setting CR0.GPCEN, wait for CR0ACK.GPCEN
completion, then setting CR0.ACCESSEN and wait for CR0ACK.ACCESSEN
completion.

refactor(cpufeat): add macro to simplify is_feat_xx_present

In this patch, we are trying to introduce the wrapper macro
CREATE_FEATURE_PRESENT to get the following capability and
align it for all the features:

-> is_feat_xx_present(): Does Hardware implement the feature.
-> uniformity in naming the function across multiple features.
-> improved readability

The is_feat_xx_present() is implemented to check if the hardware
implements the feature and does not take into account the
ENABLE_FEAT_XXX flag enabled/disabled in software.

- CREATE_FEATURE_PRESENT(name, idreg, shift, mask, idval)
The wrapper macro reduces the function to a single line and
creates the is_feat_xx_present function that checks the
id register based on the shift and mask values and compares
this against a determined idvalue.

feat(smmu): separate out smmuv3_security_init from smmuv3_init

Split the smmuv3_init() to separate smmuv3_security_init() from it in
order to allow skipping the default deny policy on reset for certain
SMMUv3 implementations.
Additionally, fix a couple of MISRA warnings.

feat(smmu): fix to perform INV_ALL before enabling GPC

The SMMU_S_INIT register definition in the Arm SMMUv3 specification
says that if SMMUv3 has REALM_IMPL == 1 then it is root firmware’s
responsibility to write to INV_ALL before enabling granule protection
checks. So fix this flow during smmuv3 init.
