usb: dwc2: Cleanup some checkpatch issues
This commmit is the result of running checkpatch --fix. The results were verified for correctness. Some of the fixes result in line over 80 char which we will fix manually later. The following is a summary of what was done by checkpatch: * Remove externs on function prototypes. * Replace symbolic permissions with octal. * Align code to open parens. * Replace 'unsigned' with 'unsigned int'. * Remove unneccessary blank lines. * Add blank lines after declarations. * Add spaces around operators. * Remove unnecessary spaces after casts. * Replace 'x == NULL' with '!x'. * Replace kzalloc() with kcalloc(). * Concatenate multi-line strings. * Use the BIT() macro.
