tegra: hwpm: add wrapper linux os structure

Browse Source 
Currently, HWPM parent structure contains linux specific device
variables. In an effort to make HWPM driver OS agnostic, create Linux
specific wrapper HWPM structure tegra_hwpm_os_linux. Move linux specific
variables from tegra_soc_hwpm structure to tegra_hwpm_os_linux
structure.
