[U-Boot] [PATCH 05/10] Exynos5420: Modify TZPC init to support 5420

[Rajeshwari S Shinde]

From: Akshay Saraswat <akshay.s at samsung.com>

Currently, part of TZPC init code for Exynos5 starts setting DECPROT
from the base address 0x10100000 upto 0x10190000 but in case of
Exynos5420 we need it to start from 0x0100E0000 and keep end address
same as 0x10190000.
