[PATCH] arm: boot: ep93xx: don't rely on machine_is_*() for removed board files

[Ethan Nelson-Moore]

Code in misc-ep93xx.h relies on machine_is_*() macros for several
boards that no longer have legacy board files. They were removed in
commit e5ef574dda70 ("ARM: ep93xx: delete all boardfiles"). This
prevents the removal of machine IDs no longer used by the kernel from
mach-types. To resolve this issue, create local copies of these macros.
(The checks themselves are still valid because the IDs are still passed
in by the bootloader on these machines.) Also take the opportunity to
remove three repeated checks for the same ID.
