The maximum frequency to bit-bang at is 7 MHz. This
puts us right on the edge. Slow down writes by
changing writel_relaxed_no_log to writel_relaxed.
Additionally, DeviceAcquire is given a single retry.
It sometimes fails the first time, but I have not
seen it fail twice. The hssp protocol for the
cypress chip is a little iffy so this gives us a better
shot at being successful everytime.
Also includes various other fixes.

uniname is a local variable having different address everytime

and also when filename reaches at maximum length, need to leave
