[PATCH v2] staging: fbtft: Fix line length warning

[himanshu bakshi <himanshu.bakshi478@gmail.com>]

From: Himanshu Bakshi <himanshu.bakshi478@gmail.com>

Hi Andy,

I have made sure that the \ (backslash) is properly aligned to the same
column as the rest of the macro. I have also taken into account your
advice and hence added a local variable for platform data.

After some thorough searching through the respective directory, I have
not found any calls for fbtft_init_dbg. This might be because it's a
helper macro that might be useful as the driver progresses.

I have also noticed that some other macros around this one have simple
style issues and if you would like, I can send another different patch
cleaning up those too.

I have also done minimal testing by using the macro once to make sure it
compiles and has no errors, if you would like, I can also run any
standalone tests for this macro.

Thanks and Regards,
	Himanshu Bakshi
