libbase/i2c: fix i2c_poll
...
Change made in 1989d85
was supposed to poll I2C devices using both
writes and reads.
Here is a sequence that was supposed to happen:
- I2C start
- start I2C write
- start I2C read
- I2C stop
Unfortunately, the change worked differently:
- I2C start
- start I2C write
- write byte of (slave_addr << 1 | 1)
- I2C stop
This way, not only did the read not happen, but a potentially harmful
write was happening.
This commit makes it so following sequence takes place:
- I2C start
- start I2C write
- if (I2C write returned NACK)
- start I2C read
- if (I2C read returned ACK)
- read 1 byte and NACK it
- I2C stop
An additional 1 byte read is happening, as some devices may be unable
to process I2C stop after initiating I2C read.

`SDRAM_TEST_DATA_BYTES` definition was incorrect as it treated size

Correct way to calculate that is to use definitions from `sdram_phy.h`.
```
#define SDRAM_TEST_DATA_BYTES (SDRAM_PHY_DFI_DATABITS / 8 * SDRAM_PHY_PHASES)
```
Also:
- extracted code to `sdram_bist_[write|read]` functions
- made global variables static
- fixed formatting
