tree-wide: use power-of-2 rounding macros where applicable

Use ROUNDUP2(), ROUNDUP2_OVERFLOW(), ROUNDUP2_DIV() and ROUNDDOWN2() at
places where the rounding argument is a variable value and we want to
leverage the implementation of these routines optimized for a
power-of-2 rounding argument.

For aligned memory buffer and DMA CAAM access, the allocated buffer size
must be rounded up to a certain value depending of the DMA behaviour on
the platform.
For the imx8qm/qxp, the allocated aligned buffer size must be rounded up
to 4 bytes.

drivers: CAAM driver User Buffer SGT create

CAAM Driver can operate directly with the User Buffer and in this
case, the buffer can be on non-contiguous physical page.

CAAM is using a DMA to load/store data from memory. The DMA is working
with physical address. In case of the User Buffer, if the buffer is
crossing multiple Small Page, a CAAM Scatter Gather Table needs to
be created to rebuild the physical memory chunks used by the User virtual
buffer.

Add a function to check if a buffer is a User buffer crossing mutliple
small page.
Add a function to create a SGT Table of the User buffer.
