tegra: hwpm: os: linux: update kernel vers. check

Browse Source 
This is needed when building HWPM driver locally without
NVIDIA build system.

- driver.c: use kernel version check to select the correct
  signature of class:devnode
- mem_mgmt_utils.c:
  - use kernel version check to provide correct parameter
    of MODULE_IMPORT_NS macro
  - use kernel version check to select the correct signature
    of get_user_pages function
- mem_mgmt_utils.h: use kernel version check to select
  between iosys-map or dma-buf-map
