USB: Remove bitmap #define from hcd.h
Using a #define to redefine a common variable name is a bad thing,
especially when the #define is in a header. include/linux/usb/hcd.h
redefined bitmap to DeviceRemovable to avoid typing a long field in the
hub descriptor. This has unintended side effects for files like
drivers/usb/core/devio.c that include that file, since another header
included after hcd.h has different variables named bitmap.
Remove the bitmap #define and replace instances of it in the host
controller code. Cleanup the spaces around function calls and square
brackets while we're at it.
