[U-Boot] [PATCH 05/13] powerpc: Remove __ilog2_u64 and ffs4 from bitops

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@freescale.com>

Remove __ilog2_u64 and ffs4 from powerpc bitops to align with the
kernel implementation.

Add the required headers that provide these function prototypes.
