core: drivers: nxp: bit shift the ITS and SB bits when reading the SFP

- The Intent to Secure (ITS) and Secure Boot (SB) flags are written to a
given pointer in ls_sfp_get_its() and ls_sfp_get_sb() respectively.
- The written values are equivalent to the entire masked OSPR0 and OSPR1
registers.
- The two functions should instead update a pointer with a boolean
integer containing the bit shifted value of the desired flag.

core: drivers: nxp: update LX series SFP fuse timeout

- The LX series manual specifies that fusing the SFP can take up to
100ms to complete.
- The fuse timeout in the LS SFP driver should be changed to 150ms
so that the possible 100ms timeout has a buffer to interpret errors.

core: drivers: nxp: Add LX series SFP driver

- Implement reading and writing to the NXP LX2160-series Security Fuse
Processor (SFP).
- Add the CFG_LS_SFP flag to enable building the SFP driver.
- The SFP driver should be able to:
- Read the entire SFP.
- Read the debug level.
- Read the Intent to Secure (ITS) and Secure Boot (SB) flags.
- Read individual OEM Unique Scratch Pad Fuse (OUID) registers.
- Read individual Super Root Key Hash (SRKH) registers.
- Set the debug level.
- Set the device to permanently program the fuse block by
setting the ITS and SB flags.
- Set individual OUID registers.
- Get the status of the SFP driver itself.
- Update fsl-lx2160a device tree with sfp and gpio nodes.
