[PATCH AUTOSEL 4.19 080/128] media: saa7134: fix terminology around saa7134_i2c_eeprom_md7134_gate()

[Sasha Levin]

From: "Maciej S. Szmigiero" <mail@xxxxxxxxxxxxxxxxxxxxx>

[ Upstream commit 9d802222a3405599d6e1984d9324cddf592ea1f4 ]

saa7134_i2c_eeprom_md7134_gate() function and the associated comment uses
an inverted i2c gate open / closed terminology.
Let's fix this.
