sxmo/sxmo-utils: workaround for kernel bug on suspend (MR 1676)

Browse source 
Removed 2 actions cause future suspends to trigger a kernel bug that
ends up spamming the kernel log with "ehci-platform 1c1b000.usb: port 1
resume error -110" and eventually makes the device not respond to any
input or hang in shutdown/reboot.

Workaround for issue: #848

Subject: [PATCH] enable bluetooth and modem drivers during crust suspend
With the megi 5.9 kernel and other suspend-related merge requests in
postmarketos, disabling these drivers is no longer needed. All of this
should result in a more reliable suspending system.
