Building HWPM with Linux v5.14 currently fails because the arguments passed to the dma_buf_vmap and dma_buf_vunmap functions is incorrect. The arguments passed to the dma_buf_vmap and dma_buf_vunmap functions were actually updated in Linux kernel version v5.11 and not v5.15. So correct the kernel version in the HWPM driver so that the correct version of the APIs are used for Linux kernels v5.11+. Finally, drop the kernel version check around the inclusion of module.h and the import of the module namespace because this is not necessary.
