mfd: atmel-flexcom: Use .resume_noirq
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.
Fixes: 7fdec11015c3 ("atmel_flexcom: Support resuming after a chip reset")
