Series ARM: move lpc32xx and dove to multiplatform | expand

Commit Message

Arnd Bergmann July 31, 2019, 7:56 p.m. UTC 
The dove platform is now ready to be enabled for multiplatform
support, this patch does the switch over by modifying the Kconfig file,
the defconfig and removing the last mach/*.h header that becomes obsolete
with this.

This work was originally done in 2015 as all the ARMv7 machiens
gove moved over to multiplatform builds, but at the time it conflicted
with some patches that Russell was trying to upstream, so we
left it at that.

I hope that there is no longer a need to keep dove separate from the
rest, so we can either add it to the other ARMv7 platforms, or just
replace it with the DT based platform code for the same hardware
in mach-mvebu and remove mach-dove entirely.
