broadcom: replace redefined ALIGN() macro with common util functions

broadcom: replace redefined ALIGN() macro with common util functions

`cl_aligned_packet_length()` expand literals, so use ALIGN_POT to compute it
at compile time.

`v3dv_AllocateMemory()` uses a 64-bit `allocationSize`, so use `align64()`.

`v3d_lower_nir()` uses a 32-bit `shared_size`, so use `align()`.
