H616 DRAM support on mailine kernel

[project-tvbox project-tvbox]

dears,

How can I edit the drm parameters directly in the mainline kernel,
since the mainline dts does not have these options like the legacy
one, I saw that the dram.c drives in the legacy and mailline are
similar, for example:
[dram_para]
dram_clk = 600
dram_type = 3
dram_dx_odt = 0x03030303
dram_dx_dri = 0x0e0e0e0e
dram_ca_dri = 0x1f12
dram_odt_en = 1
dram_para1 = 0x30fb
dram_para2 = 0x0000
dram_mr0 = 0x840
 in the mainline kernel
