[PATCH v3 0/4] update clock handler and proper cpu features

[Sagar Shrikant Kadam]

U-Boot cmd "cpu detail" shows inconsistent CPU features and is missing
clk_request and free handlers.
The current "cpu detail" sometimes shows "Microcode" as a feature, which
is not the case with FU540-C000 on HiFive Unleashed board.

Patch 1: add clk request handler to check if valid clock id is requested.
Patch 2: add cpu node aliases. 
Patch 3: Correctly parse and update mmu-type.

RISC-V core's on FU540-C000 SoC have separate instruction and data (split) 
L1 cache.
Patch 4:Use i-cache-size dt property as one of identifier to indicate a
	split cache is available.

I have picked few dependent patches from Sean's and Pragnesh's latest
series from here [1]...[5].

These have applied on mainline U-Boot commit 0d8f35b58cc8 
("Merge https://gitlab.denx.de/u-boot/custodians/u-boot-spi")

Patch history:
=============================================
V3:
1. Included the cosmetic change as suggested

2. Added Reviewed-By tags

V2:
1. Incorporate review comments from Bin and Sean Anderson. 
   and dropped 2nd patch as similar work was already done in [1] and [2]
2  Add cpu node aliases to display cpu node's in sequence.
3. Add fix to show mmu as available cpu feature. 
4. Check and append L1 cache feature.
