Gwendal Grignou fc948409cc iio: sx9310: Fix write_.._debounce() 
Check input to be sure it matches Semtech sx9310 specification and
can fit into debounce register.
Compare argument writen to thresh_.._period with read from same
sysfs attribute:

Before:                   Afer:
write   |  read           write   |  read
-1      |     8           -1 fails: -EINVAL
0       |     8           0       |     0
1       |     0           1       |     0
2..15   |  2^log2(N)      2..15   |  2^log2(N)
16      |     0           >= 16 fails: -EINVAL
