tegra: hwpm: Fix build for Linux v5.18

Browse Source 
Upstream commit 7938f4218168 ("dma-buf-map: Rename to iosys-map")
renames 'struct dma_buf_map' to 'struct iosys_map' and this causes the
HWPM driver build to fail for Linux v5.18 and greater. Fix this by using
the appropriate structure name depending on kernel version.
