Enable LTO for some boards that were tested by people on U-Boot Mailing List.
I have also confirmed this works on the r8a774a1_beacon board as well and boots without issues. The r8a774b1_beacon and r8a774e1_beacon should be safe since the only real difference between them is the device tree reference.
The RZ/G2 boards from Beacon don't use SPL, but wIthout LTO: U-Boot 784324
With LTO: U-Boot 757202
For a reduction of: -27122 (-3.46%)
