Staging: solo6x10: Replace expressions that don’t use ALIGN macro 

Author: Andreea-Cristina Bernat <bernat.ada@gmail.com>

There are some expressions that compute the roundup of a number, but don't use
the existing macro defined in /include/kernel.h. This patch uses the following
Coccinelle semantic patch:
@ haskernel @
@@

@ depends on haskernel @
expression E1, E2;
@@

- (E1 + (E2 - 1)) & ~(E2 - 1)
+ ALIGN(E1, E2)
