Current ARM SMMU probe functions intermingle HW and DT probing
in the initialization functions to detect and programme the ARM SMMU
driver features. In order to allow probing the ARM SMMU with other
firmwares than DT, this patch splits the ARM SMMU init functions into
DT and HW specific portions so that other FW interfaces (ie ACPI) can
reuse the HW probing functions and skip the DT portion accordingly.

This patch implements no functional change, only code reshuffling.

Although I'd also like Robin to have a look at this.

Sorry, I've been slow this week. Having finally got round to taking a
proper look, I swear this seems even tidier than the last version I
looked at closely. It doesn't break DT boot on my Juno, either.
