3d28c0182d travis: add a branch whitelist with just 'master'.
Travis allows us to build on branch updates and on PRs. Right now our process is to build always on PRs, but to manually only build 'master' when we know that riscv-tools has been bumped (because that rebuilds the master cache which holds riscv-tools). But this is an annoying and error-prone processes that requires extra admin permissions.

With this change, i think we can just leave "Build Branch Updates" to "ON" and get the same effect we are currently doing manually, because only on update to master branch will it do a build. PRs to master branch will get a build. PRs to other branches will I believe NOT get a build.

0668f13d99 debug: Fix race between resumereq and resumeack
For an arbitrary DMI master on a fast clock running against a core
on a slow clock, there was a race between writing resumereq and
reading resumeack. When using JTAG DTM this does not occur in practice,
but clean it up for running simulations with FESVR and future DMI masters.
