The use of state->CH_Ctrl[i].size in a shift operation implies that its
value can be as much as 32, but the state->CH_Ctrl[i].val array is only
25 in size. Bounds check the size before shifting and looping. Fixes
warnings seen with GCC 13:
../drivers/media/tuners/mxl5005s.c: In function 'MXL_ControlWrite_Group.isra':
../drivers/media/tuners/mxl5005s.c:3450:70: warning: array subscript 32 is above array bounds of 'u16[25]' {aka 'short unsigned int[25]'} [-Warray-bounds=]
3450 | state->CH_Ctrl[i].val[j] = (u8)((value >> j) & 0x01);
| ~~~~~~~~~~~~~~~~~~~~~^~~
../drivers/media/tuners/mxl5005s.c:238:13: note: while referencing 'val'
238 | u16 val[25]; /* Binary representation of Value */
