Subject: [PATCH] staging: fbtft: remove unnecessary braces in if statements and space before close parenthesis in function call

Adhere to Linux kernel coding style.

Reported by checkpatch:

CHECK: Unnecessary parentheses around 'devcode != 0x0000'
CHECK: Unnecessary parentheses around 'devcode != 0x9320'
CHECK: Unnecessary parentheses around 'par->info->var.xres == 320'
CHECK: Unnecessary parentheses around 'par->info->var.yres == 240'
CHECK: Unnecessary parentheses around 'par->spi->bits_per_word == 8'
CHECK: Unnecessary parentheses around '!txbuflen'
CHECK: Unnecessary parentheses around 'bpp > 8'
ERROR: space prohibited before that close parenthesis ')'
