[U-Boot] [PATCH] sifive: riscv: streamline HiFive Unleashed configuration infrastructure

[Sagar Shrikant Kadam <sagar.kadam@sifive.com>]

This patch is intended to update the current configuration implementation of HiFive
Unleashed board so that it is as per the guidelines provided in U-boot's doc/README.kconfig.
The board has a FU540-C000 SoC built around U54-MC Core complex.

This patch is based on the commit 75551c8bfc95 ("Merge branch '2019-07-26-ti-imports'")
in master branch of repo[1] and is tested with OpenSBI to use the dtb passed as argument 
in FW_PAYLOAD_FDT_PATH from the mainline kernel and boot's linux image over tftp.
The patch is available for testing at dev/sagark/sifive_u540defconfig branch here [2].

Summary:
-Update TARGET in board select menu.
-Update SYS_CPU from generic to u54-mc.
-Added SYS_SOC.
-Update SYS_BOARD from fu540 to hifive_unleashed.
-Update SYS_CONFIG_NAME from sifive-u540 to hifive_unleashed .
-Update MAINTAINERS file with relevant entries corresponding to the above changes.

This patch will conflict with few patches which are already submitted for review,
it would be good if U-boot folks would suggest something accordingly.
