Commit 740d5d3 added two new features but only one feature name,
which results in NULL prints when device_id feature is selected.
Before:
HG556a # cpu detail
-1: cpu at 0 BCM6358A1
ID = 0, freq = 300 MHz: L1 cache, MMU, NULL
Device ID 0x2a010
-1: cpu at 1 BCM6358A1
ID = 1, freq = 300 MHz: L1 cache, MMU, NULL
Device ID 0x2a010
After:
HG556a # cpu detail
-1: cpu at 0 BCM6358A1
ID = 0, freq = 300 MHz: L1 cache, MMU, Device ID
Device ID 0x2a010
-1: cpu at 1 BCM6358A1
ID = 1, freq = 300 MHz: L1 cache, MMU, Device ID
Device ID 0x2a010

v3: No changes.
v2: Introduce changes suggested by Daniel Schwierzeck:
- Add the missing name instead of checking for null names.

Add a new sysreset driver based on linux/drivers/power/reset/syscon-reboot.c,
which provides a generic driver for platforms that only require writing a mask
to a regmap offset.
Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>

v4: Rebased.
v3: Introduce changes suggested by Simon Glass:
- Add missing driver description.
- Alphabetically order includes.
- Add priv struct to store regmap during probe.
- Cosmetic fixes.
v2: No changes.

Use uclass_first_device and uclass_next_device in order to avoid exceptions
for drivers that aren't probed when cpu ops are requested.
Improve code style and fix indentations.
Fix incorrect line break when cpu info is not available.
Remove unneeded brackets.
Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>

v4: Refactor code to use uclass_first_device and uclass_next_device as
requested by Simon Glass.
v3: add new patch to ensure that device is probed.

v4: No changes.
v3: Several improvements:
- Probe driver correctly.
- Allocate size for priv struct.
- Cosmetic fixes.
v2: Introduce changes suggested by Daniel Schwierzeck:
- Split BMIPS support patches.
- Get register base from DT.

v4: No changes.
v3: Select CONFIG_REMAKE_ELF.
v2: Introduce changes suggested by Daniel Schwierzeck:
- Split BMIPS support patches.
- Replace initdram with dram_init.
- Merge with "fix first CPU check" patch.
