warp7: Fix the write to the LDOGCTL PMIC register
The third parameter of the pmic_clrsetbits() function is the mask
to the register and the correct mask is 1 not 0.
Since the LDOGCTL only contains a single valid bit (bit 0),
we can use pmic_reg_write() and write 1 directly, which fixes
the problem in a simpler way and use the original pmic function
that was used prior to the DM PMIC conversion.

ARM: dts: rmobile: Zap redundant USB/SDHI nodes on M3N
v2019.01 commit cbff9f80cedd ("ARM: dts: rmobile: Sync Gen3 DTs with
Linux 4.19.6") made the sdhi/usb nodes available in r8a77965.dtsi.
Hence, remove the SDHI/USB nodes from r8a77965-u-boot.dtsi. This is
equivalent to partially reverting below v2019.01 commits:
- f529bc551b6d ("ARM: dts: rmobile: Extract USB nodes on M3N")
- 830b94f76867 ("ARM: dts: rmobile: Extract SDHI nodes on M3N")
Duplicating the nodes from <soc>.dtsi to <soc>-u-boot.dtsi is obviously:
- not needed if no U-boot-specific changes are needed in those nodes.
- potentially dangerous/error-prone, since the duplicated properties
override the properties originally defined in <soc>.dtsi. One
possible consequence is that <soc>.dtsi is getting an update from
Linux, while <soc>-u-boot.dtsi stays unchanged. In this situation,
the obsolete property values from <soc>-u-boot.dtsi will take
precedence masking some of the <soc>.dtsi updates, potentially
leading to all kind of obscure issues.
Below is the dtdiff of r8a77965-salvator-x-u-boot.dtb (the only "user"
of r8a77965-u-boot.dtsi) before and after the patch (slightly
reformatted to avoid 'git am/apply' issues and to reduce the width).
What below output means is there is already a mismatch in some of
SDHI/USB nodes between r8a77965.dtsi and r8a77965-u-boot.dtsi. Since no
U-Boot customization is needed in SDHI/USB DT nodes, get rid of them in
r8a77965-u-boot.dtsi.
The update didn't fully work on R-Car3 due to the
CONFIG_SYS_BOOTMAPSZ=8MiB definition left by v2016.09 commit e525d34b476e ("ARM: rmobile: Add support salvator-x board"),
