drm/i915/bios: Apply vlv_fixup_mipi_sequences() to v2 mipi-sequences too

It turns out that the fixup from vlv_fixup_mipi_sequences() is necessary
for some DSI panel's with version 2 mipi-sequences too.

Specifically the Acer Iconia One 8 A1-840 (not to be confused with the
A1-840FHD which is different) has the following sequences:

BDB block 53 (1284 bytes) - MIPI sequence block:
	Sequence block version v2
	Panel 0 *

Sequence 2 - MIPI_SEQ_INIT_OTP
	GPIO index 9, source 0, set 0 (0x00)
	Delay: 50000 us
	GPIO index 9, source 0, set 1 (0x01)
	Delay: 6000 us
	GPIO index 9, source 0, set 0 (0x00)
	Delay: 6000 us
	GPIO index 9, source 0, set 1 (0x01)
	Delay: 25000 us
	Send DCS: Port A, VC 0, LP, Type 39, Length 5, Data ff aa 55 a5 80
	Send DCS: Port A, VC 0, LP, Type 39, Length 3, Data 6f 11 00
	...
	Send DCS: Port A, VC 0, LP, Type 05, Length 1, Data 29
	Delay: 120000 us

Sequence 4 - MIPI_SEQ_DISPLAY_OFF
	Send DCS: Port A, VC 0, LP, Type 05, Length 1, Data 28
	Delay: 105000 us
	Send DCS: Port A, VC 0, LP, Type 05, Length 2, Data 10 00
	Delay: 10000 us

Sequence 5 - MIPI_SEQ_ASSERT_RESET
	Delay: 10000 us
	GPIO index 9, source 0, set 0 (0x00)

Notice how there is no MIPI_SEQ_DEASSERT_RESET, instead the deassert
is done at the beginning of MIPI_SEQ_INIT_OTP, which is exactly what
the fixup from vlv_fixup_mipi_sequences() fixes up.

Extend it to also apply to v2 sequences, this fixes the panel not working
on the Acer Iconia One 8 A1-840.
