Pawel Dembicki cdc1090084 ramips: mt7620: add kernel size for Jboot devices 
Since few months multiple users reported problems with various JBoot
devices. [0][1][2][3] All of them was bricked.

On my Lava LR-25G001 it freezes with current snapshot:

CDW57CAM_003 Jboot B695
Giga Switch AR8327 init
AR8327/AR8337 id   ==> 0x1302
JRecovery Version R1.2 2014/04/01 18:25
SPI FLASH: MX25l12805d 16M
.
.
(freeze)

The kernel size is >2048k.

I built current master with minimal config and it boots well:

CDW57CAM_003 Jboot B695
Giga Switch AR8327 init
AR8327/AR8337 id   ==> 0x1302
JRecovery Version R1.2 2014/04/01 18:25
SPI FLASH: MX25l12805d 16M
.
...........................
Starting kernel @80000000...
[    0.000000] Linux version 5.4.124

Kernel size is <2048k.

Jboot bootloader isn't open source, so it's impossible to find
solution in code. It looks, that some buffer for kernel have 2MB size.

To avoid bricked devices, this commit introduces 2048k limit kernel
size for all jboot routers.
