KCONFIG CHANGES IN NCS V1.6

[WesC]

i was running some power optimization and MTU tests in NCS V1.5.1 and was able to compile and run.

 I upgraded to NCS V1.6.0 and there were several errors

So when I compile now I get several KCONFIG errors and it fails.

 C:/Users/Wes/prj.conf:114: warning: attempt to assign the value '252' to the undefined symbol BT_L2CAP_RX_MTU

 C:/Users/Wes/prj.conf:115: warning: attempt to assign the value '260' to the undefined symbol BT_RX_BUF_LEN

 C:/Users/Wes/prj.conf:130: warning: attempt to assign the value 'y' to the undefined symbol PM_DEEP_SLEEP_STATES

 C:/Users/Wes/prj.conf:131: warning: attempt to assign the value 'y' to the undefined symbol PM_STATE_LOCK

 I cannot find documentation on what(if any) are the replacements for these or how do you replicate this in NCS V1.6

 It seems like these was removed by this PR:

https://github.com/nrfconnect/sdk-zephyr/commit/6483e12a8ac4f495b28279a6b84014f633b0d374#diff-c3d67d3b007aaa43e5325dc2ecfaf5091d493ee66ca7567d03ff2b01d9afce9aL8

It seems like most of the samples just comments these out (and adds CONFIG_BT_BUF_ACL_RX_SIZE)

samples/subsys/mgmt/mcumgr/smp_svr/overlay-bt.conf

samples/subsys/mgmt/mcumgr/smp_svr/overlay-bt-tiny.conf

samples/net/lwm2m_client/overlay-bt.conf

C:/Users/Wes/prj.conf:131: warning: attempt to assign the value 'y' to the undefined symbol PM_STATE_LOCK

It seems like this Kconfig was removed when moving subsys/power to subsys/pm: 

https://github.com/nrfconnect/sdk-zephyr/commit/86a624e2a2793111f7099c31cb473d1617e5ee1e 

I think you can just remove this Kconfig, like the sample zephyr/samples/boards/nrf/system_off/prj.conf did.

Best regards,
