Flexcom IP embeds 3 other IPs: usart, i2c, spi and selects the operation mode (usart, i2c, spi) via mode register (FLEX_MR). On i2c bus there might be connected critical devices (like PMIC) which on suspend/resume should be suspended/resumed at the end/beginning. i2c uses .suspend_noirq/.resume_noirq for this kind of purposes. Align flexcom to use .resume_noirq as it should be resumed before the embedded IPs. Otherwise the embedded devices might behave badly.
