gpu: nvgpu: Correct LS ucode data alignment.

Browse Source 
Currently LS UCODE data is aligned to PAGE_SIZE
which is dependent on kernel config.

This causes "data_size" variable to change due to
padding difference which causes LS sig authentication
to fail.

This patch corrects alignment and align it to
LSF_UCODE_DATA_ddALIGNMENT instead of PAGE_SIZE.
