ufs: Fix Tegra UFS for Linux v6.13

Browse Source 
In Linux v6.13, the quirk definition 'UFSHCD_QUIRK_BROKEN_64BIT_ADDRESS'
was removed and replaced with a function pointer than can be used to set
the DMA mask as needed for a given device. Update the Tegra UFS driver
to fix support for Linux v6.13. Note that prior to Linux v6.13, the flag
'UFSHCD_QUIRK_BROKEN_64BIT_ADDRESS' would set the DMA mask to 32-bits
and so this change is equivalent to the configuration of prior kernels.
