Remove IAR supported from targets failing IAR 8.32 build

Few targets have libraries compatible to IAR 7.x, which fail with
IAR 8.x, IAR support for them is removed till updated library is
added.

CI failure seen if IAR is not added as supported target, trying with
release_version as empty string

List of targets affected:

1. UBLOX_EVK_ODIN_W2
2. MTB_UBLOX_ODIN_W2
3. MBED_CONNECT_ODIN
4. MTB_MXCHIP_EMW3166
5. MTB_ADV_WISE_1530
6. MTB_USI_WM_BN_BM_22
7. REALTEK_RTL8195AM
