[Qemu-devel] [PATCH V2 02/10] hw/sd.c: convert binary variables to bool

[Igor Mitsyanko]

Several members of SDState have type int when they actually are binary 
variables.
Change type of these variables to bool to improve code readability. Change SD 
API
to be in consistency with new variables type.
