Is your enhancement proposal related to a problem? Please describe.CONFIG_BT_ISO_TX_MTU today is not used by the host.
It has 3 uses
1) Many samples and tests are using this value to define their TX buffer pools
2) hci_raw.c uses it to define the size of the hci_iso_pool.
3) The controller optionally uses it to determine the HCI ISO TX buffer size, but CONFIG_BT_CTLR_ISO_TX_BUFFER_SIZE can be directly for that too
Describe the solution you'd like
Remove the Kconfig as the host doesn't it and the applications shouldn't. For hci_raw and the HCI ISO tx buffer sizes we can/should use CONFIG_BT_CTLR_ISO_TX_BUFFER_SIZE.
