ARM: omap2: simplify allocation for omap_device

Use a flexible array member (FAM) to combine hwmods array allocation
with the omap_device structure. This reduces the number of allocations
from two separate calls (one for the device, one for the array) to a
single allocation, improving efficiency and reducing memory fragmentation.

The FAM approach also enables bounds checking through __counted_by(),
which provides runtime verification that array accesses stay within
the allocated size. This improves security and helps catch bugs during
development.

Simplify error handling by removing the unnecessary multi-label goto
pattern. The new code is more straightforward: allocate, verify, copy
data, and either return success or error immediately.

Also removes the now-redundant kfree(od->hwmods) in omap_device_delete()
since the hwmods array is now embedded in the structure rather than
separately allocated.
