qcacmn: Enable dynamic puncture for DFS radar

1. Enable sub chan DFS type if QCA_DFS_BW_PUNCTURE defined, or all bonded
operation freq will be affected and disabled for nol, puncture can't work,
always need to switch freq.

2. Find nearest puncture pattern for a bitmap.
For example, SAP started with channel width 320 MHz, if only 20 MHz freq
affected by radar, 320 + 20 puncture pattern is invalid, but puncture
pattern 320 + 40 can be used.

3. Fix build issue when QCA_DFS_BW_PUNCTURE defined as following.
error: incompatible pointer types passing 'qdf_freq_t[16]' (aka
'unsigned int[16]') to parameter of type 'uint16_t *' (aka 'unsigned
short *')
