With this patch we enable CONFIG_USB for HSDK, which is not explicitly
selected by UDL since the commit 5d50bd440bc2 ("drm/udl: Make udl
driver depend on CONFIG_USB"). Commit 4c13ca86dcf8 ("ARC:
[plat-hsdk]: fix USB regression") is not yet backported to Linux
kernel 5.6.x, so we enable this option in fragment file for HSDK.

Synopsys DesignWare HSDK (which stands for ARC HS
Development Kit) is the latest and greatest development
platform that sports quad-core ARC HS38 in real silicon.
Most noticeable features of the board are:
* Quad-core ARC HS38 CPU running at 1GHz
* 4Gb of DDR
* Built-in Vivante GPU (well supported via open source
Etnaviv drivers)
* Built-in Wi-Fi/Bluetooth module (RedPine RS-9113)
And as usual we have:
* [micro] SD-card slot
* 2 USB 2.0 ports
* 1Gbit Ethernet port
* Built-in Digilent JTAG probe
* Serial port accessible via micro-USB port
Writing sdcard.img on SDcard creates two partitions:
* FAT32 with uImage and uboot.env
* EXT4 with root filesystem
We modify kernel config because in default hsdk kernel config
CONFIG_INITRAMFS_SOURCE parameter is set and when we build
rootfs separately (BR2_TARGET_ROOTFS_INITRAMFS is not set)
error appears. Also we set up CONFIG_ARC_UBOOT_SUPPORT which
enables usage of uboot variables in the boot process.
[Peter: Fix comments and rename defconfig to snps_archs38_hsdk_defconfig,
Add defconfig to DEVELOPERS and fixup board/synopsys entry,
Drop postimage script, rename env file in genimage.cfg and drop size
setting for rootfs partition,
Add "" for CONFIG_INITRAMFS_SOURCE in linux fragment]
