Update flash tlul adapter

The original flash tlul adapter contained a request fifo to absorb
incoming transactions.  These transactions were then replayed
to the flash macro.

This extra outstanding capacity was not necessary as the flash macro
is already wrapped by a flash_phy controller and should itself handle
outstanding transactions if appropriate.

Flash now uses the tlul sram adapter to just pass transactions directly
through (while holding appropriate information for constructing tlul
responses to host).

A separate PR will be pushed to add parallel transaction handling to
flash_phy.  This will take advantage of flash's multi-bank construction
and long read times.
