liblitedram/sdram_spd: do not send stop symbol
...
According to the SPD specification, we shouldn't send
a stop symbol after the write that sets the address counter.

liblitedram/sdram_spd: use temp_len when reading SPD
...
This change should change anything from the point of view of
`sdram_read_spd` caller, but it makes it so less I2C reads are actually
hapenning.
With `len` we read too many bytes and write them to the `buf`.
In subsequent iterations we overwrite those bytes as all counters are
being updated by the `temp_len`. Nothing terrible, but too many
bytes were being read.
