ASoC: Remove bogus check for register validity in debugfs write

Browse Source 
Since not all registers need to be cached and the cache is entirely
optional anyway we shouldn't be checking that a register is in the
cached range. If the register is invalid then the actual I/O code
can determine that and report an error.

Similarly, the step size can and should be enforced by the lower level
code if it's important.
