[PATCH 1/2] bsps/xil: Make sleep.h a stub

[Kinsey Moore]

This makes xil/sleep.h a stub to prevent multiple differing definitions
of sleep functions from toolchain and local headers. The non-standard
sleep definitions were not in use and can be added later if needed.

-* This macro polls an address periodically until a condition is met or till the
-* timeout occurs.
-* The minimum timeout for calling this macro is 100us. If the timeout is less
-* than 100us, it still waits for 100us. Also the unit for the timeout is 100us.
-* If the timeout is not a multiple of 100us, it waits for a timeout of
-* the next usec value which is a multiple of 100us.

-* @param            IO_func - accessor function to read the register contents.
-*                   Depends on the register width.
-* @param            ADDR - Address to be polled
-* @param            VALUE - variable to read the value
-* @param            COND - Condition to checked (usually involves VALUE)
-* @param            TIMEOUT_US - timeout in micro seconds
-*
-* @return           0 - when the condition is met
-*                   -1 - when the condition is not met till the timeout period
