Kernel: Enable PCI ECAM method again if available

Browse source 
Apparently we don't enable PCI ECAM (MMIO access to the PCI
configuration space) even if we can. This is a regression, as it was
enabled in the past and in unknown time it was regressed.

The CommandLine::is_mmio_enabled method was renamed to
CommandLine::is_pci_ecam_enabled to better represent the meaning
of this method and what it determines.

Also, an UNMAP_AFTER_INIT macro was removed from a method
in the MMIOAccess class as it halted the system when the kernel
tried to access devices after the boot process.
