spi/spi-pl022: Resolve formatting issues
There were few formatting related issues in code. This patch fixes them. Fixes include: - Remove extra blank lines - align code to 80 cols - combine several lines to one line - Replace multiple spaces with tabs - Remove spaces before labels Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Tested-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
