latest master does not boot for feather_m0_adalogger

[jerryneedell]

I tried loading the current master build for the feather_m0_adalogger onto a feather_bluefruit_m0 but it failed to boot. reverting to a 20181105 build does work.
Note; the adalogger build is recommended for the Bluefruit for use with the BLESPI library - see:

Following up on #1326 and #1327:

Made some CPX builds to test NeoPixels.
168e23e and after don't work: no REPL
9d91111 does not seem to build: I get this error:

FYI - tried commit f190bb2 on several boards,
the MetroM4 express and TrellisM4 both appear to be working well.
None of the M0 boards tested will boot to present CIRCUITP
tried feather_m0_express,CPX,feather_m0_adalogger,metro_m0_express
Also tried pca10059 -- no luck there either.
