Note: LPC55(S)1x/2x/6x need update power_lib library to SDK2.8.2 or latest one

For LPC55(S)1x/2x/6x users, please update your fsl_power_lib to SDK2.8.2.

The previous SDK(2.6.x and 2.7.x)'s power library have two known function bugs, 

1. FRO trim value can not be recovery correctly after wakeup from deep-sleep / power-down / deep power-down.

   -- this means the 12MHz FRO frequency is different for after boot-process(11.99 MHz for example) and wakeup from low-power modes(11.89MHz for example). 

   -- The reason is the FRO trim value not recovery after wakeup. 

2. Cap-bank value can not be set correctly by use power lib capbank trim API.

   -- This is a software bug which fixed in SDK2.8.2 already.

Just replacement the power_lib library file should be workable for most of customers. the API should be compatible.

Thank you!
