x86, pic: Make use of legacy_pic abstraction
This patch replaces legacy PIC-related global variable and functions with the new legacy_pic abstraction. Signed-off-by: Jacob Pan <jacob.jun.pan@intel.com> LKML-Reference: <43F901BD926A4E43B106BF17856F07559FB80D04@orsmsx508.amr.corp.intel.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* make i8259 a driver so that we can select pic functions at run time. the goal
