mb/purism/librem*: drop EC chip device

CB:35086 exposed that the devicetree listed an EC chip for which there
is no actual driver; the EC is entirely ACPI code (.asl) included by
the board's ec.asl. Remove the unnecessary EC chip driver from both
boards, as well as the unnecessary Kconfig selection for librem_bdw.

Test: build/boot Librem 13v1, 13v4, verify battery info etc still correct.
