|size|: The size of the read (default: 128 bytes). The max size for a

read is |READBAR_MAX_SIZE|.

Errors:

|ZX_ERR_NOT_FOUND|: |device| was not found, or |bar_id| did not exist in |device|.

|ZX_ERR_INVALID_ARGS|: |bar_id| is invalid, or offset / size combined

are invalid for the given BAR's size.

|ZX_ERR_NOT_SUPPORTED|: The BAR specified by |bar_id| is not an MMIO BAR.
