misc: rtsx: Remove deadcode

Browse source 
The last uses of rtsx_ms_power_off_card3v3() and
rtsx_sd_power_off_card3v3() were removed by 2019's
commit bede03a579 ("misc: rtsx: Enable OCP for rts522a rts524a rts525a
rts5260")

The last use of rtsx_pci_transfer_data() was removed by 2024's
commit d0f459259c ("memstick: rtsx_pci_ms: Remove Realtek PCI memstick
driver")

Remove them.
