[PATCH v2] staging: rts5208: Clean up coding style in rtsx_chip.c to get rid of checkpatch.pl warnings and combine two ifs into one

[Giedrius Statkevicius]

Fix 10 occurences of coding style errors where the line exceeds 80 characters by breaking them into more lines.
Checkpatch.pl reports these errors as: 'WARNING: line over 80 characters'
Also, removes unnecessary returns in two void functions by removing the return statements.
Checkpatch.pl reports these errors as: 'WARNING: void function return statements are not generally useful'
Lastly it combines two if statements into one in rtsx_reset_chip()

Patch is against Greg KH's staging-next tree.

Changes in v2:
  - Combines two if statements into one in rtsx_reset_chip() (thanks Dan Carpenter)
  - Aligns the second line of a if statement to the opening parenthesis in rtsx_polling_func() (thanks Dan Carpenter)
