Clean up #ifs

Replace #if CONFIG_FOO==1 with #if CONFIG_FOO:
find src -name \*.[ch] -exec sed -i "s,#if[[:space:]]*\(CONFIG_[A-Z0-9_]*\)[[:space:]]*==[[:space:]]*1[[:space:]]*\$,#if \1," {} +

Replace #if (CONFIG_FOO==1) with #if CONFIG_FOO:
find src -name \*.[ch] -exec sed -i "s,#if[[:space:]]*(\(CONFIG_[A-Z0-9_]*\)[[:space:]]*==[[:space:]]*1)[[:space:]]*\$,#if \1," {} +

Replace #if CONFIG_FOO==0 with #if !CONFIG_FOO:
find src -name \*.[ch] -exec sed -i "s,#if[[:space:]]*\(CONFIG_[A-Z0-9_]*\)[[:space:]]*==[[:space:]]*0[[:space:]]*\$,#if \!\1," {} +

Replace #if (CONFIG_FOO==0) with #if !CONFIG_FOO:
find src -name \*.[ch] -exec sed -i "s,#if[[:space:]]*(\(CONFIG_[A-Z0-9_]*\)[[:space:]]*==[[:space:]]*0)[[:space:]]*\$,#if \!\1," {} +

(and some manual changes to fix false positives)
