This patch series backports changes on Aspeed I2C driver from upstream
v5.1 tree to support multi-master bus environment stably.

To enable the multi-master configuration with this patch, each platform's
dt overlay should have 'multi-master' setting like below example:

&i2c5 {
	multi-master;
	status = "okay";
};
