Structure ufs_dev_params is actually used in UFS host drivers to declare host specific power mode parameters, like ufs_<vendor>_params or host_cap, which makes the code not very straightforward to read. Rename the structure ufs_dev_params to ufs_host_params and unify the declarations in all drivers to host_params. In addition, rename the two functions ufshcd_init_pwr_dev_param() and ufshcd_get_pwr_dev_param() which work based on the ufs_host_params to ufshcd_init_host_params() and ufshcd_negotiate_pwr_params() respectively to avoid confusions. This change does not change any functionalities or logic.
