[PATCH 3/3] aspeed/smc: Fix number of dummy cycles for FAST_READ_4 command

[Guenter Roeck]

The Linux kernel recently started using FAST_READ_4 commands.
This results in flash read failures. At the same time, the m25p80
emulation is seen to read 8 more bytes than expected. Adjusting the
expected number of dummy cycles to match FAST_READ fixes the problem.
