Subject: [PATCH v5 0/8] i2c: i2c-mlxbf.c: bug fixes and new feature support

This is a series of patches fixing several bugs and implementing
new features.

Bug fixes:
1) Fix the frequency calculation
2) Fix incorrect base address passed during io write
3) prevent stack overflow in mlxbf_i2c_smbus_start_transaction()
4) Support lock mechanism to avoid race condition between entities
   using the i2c bus

Cleanup:
5) remove IRQF_ONESHOT flag as it is no longer needed.

Features:
6) Support multi slave functionality
7) Support BlueField-3 SoC
8) Update binding devicetree

What has changed from v4->v5:
Fix build error in the mellanox i2c device tree documentation
