drivers: Flag mixed declarations and code

Browse Source 
Adding the build flag '-Werror=declaration-after-statement' to prevent
mixing variable definitions within the body of code. Ideally, we would
enable this for all kernels, but in the latest upstream Linux kernels
this flag has been removed from the kernel build to allow for scope
based declarations in some contexts. However, even in the upstream
kernel declaring variables at the start of the scope is recommended. Add
this flag for noble kernels to ensure that this recommendation is
followed for OOT drivers.
