zephyr: macros: manage macro redefinition between SOF and Zephyr Some common macros are defined both in SOF and Zephyr. Temporarily undef local copies if they are already defined in Zephyr. This will be removed once Zephyr integration is complete as Zephyr copies will be used directly. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>

Fixes for macros used for bit masks creation. Bit mask setting macros for for specific parameters were expanded in a way that was causing unexpected compiler behaviour. Specifically: literal 1 was treated as 32bit integer ((1 << ((b_hi)-(b_lo) + 1)) -1) was expanded to shift the 32bit integer by 32. ((1 << (31 - 0 + 1)) -1) Macro MASK() was was missing left shift.
