[U-Boot] [PATCH V3 02/10] waitbit: Add the generic wait_for_bit macros for 16 and 32 bits.

From: Kursad Oney <kursad.oney at broadcom.com>

wait_for_bit_le32 and wait_for_bit_le16 use the raw I/O functions
which would default to big-endian on BE systems. Create the generic
equivalents to use the native endianness.
