The configuration struct of A64 EMMC(MMC2) compatible used to
have the needs_new_timings variable missing, which lead to NULL
pointer dereference now when trying to set up the old timings mode, as
the old timings mode doesn't exist at all on A64.

Fix this issue by adding this variable and setting it to true in
the configuration struct.

Fixes: 4fb3ce07eafa ("mmc: sunxi: Add EMMC (MMC2) controller compatible")
