Depending on kernel version the Tegra UFS driver includes different headers to build the driver. Now that Linux v5.x kernels are no longer supported, we can simplify this. Simplify the headers for the Tegra UFS driver as follows ... 1. For Linux v6.x kernels only the ufshcd-priv.h and ufshcd-pltfrm.h headers are required. These headers are copied from the Linux kernel. However, only the prototypes for the functions 'ufshcd_query_attr', 'ufshcd_query_descriptor_retry' and 'ufshcd_pltfrm_init' are needed. The functions 'ufshcd_query_attr' and 'ufshcd_query_descriptor_retry' have not been change since they were introduced in Linux v4.17 and the function 'ufshcd_pltfrm_init' was last updated in Linux v6.1 (making the ufs_hba_variant_ops argument const). Although redefining the prototypes outside the kernel is fragile and does not protect the Tegra UFS driver from updates to these functions, this problem already exists. 2. Move the files ufshcd-pltfrm.h and ufshcd-priv.h into the Tegra UFS driver directory because these are not needed outside of the driver.
