ca52a25882
This patch adds the new, faster architectural register accessors to libpayload that were already added to coreboot in CB:27881. It also hardcodes the assumption that coreboot payloads run at EL2, which has already been hardcoded in coreboot with CB:27880 (see rationale there). This means we can drop all the read_current/write_current stuff which added a lot of unnecessary helpers to check the current exception level. This patch breaks payloads that used read_current/write_current accessors, but it seems unlikely that many payloads deal with this stuff anyway, and it should be a trivial fix (just replace them with the respective _el2 versions). Also add accessors for a couple of more registers that are required to enable debug mode while I'm here.
